Systems And Methods To Dynamically Calibrate And Adjust Gains In A Direct Conversion Receiver

View page
US Patent:
20160380788, Dec 29, 2016
Filed:
Jun 25, 2015
Appl. No.:
14/749884
Inventors:
- AUSTIN TX, US
STEVEN M. BOSZE - CEDAR PARK TX, US
KEITH A. TILLEY - AUSTIN TX, US
KEVIN B. TRAYLOR - AUSTIN TX, US
International Classification:
H04L 25/06
Abstract:
Method embodiments are provided herein for dynamically calibrating and adjusting a direct conversion receiver system. One embodiment includes applying one or more gain control signals to one or more gain elements of a receiver system, where the applying one or more gain control signals results in a gain change to the receiver system; in response to the gain change, determining whether the receiver system exhibits a DC (direct conversion) offset; and in response to a determination that the receiver system exhibits the DC offset, applying one or more DC offset correction control signals to one or more gain elements of the receiver system, where the one or more DC offset correction signals are configured to correct the DC offset.

Techiques For Time-Domain Frame Synchronization Of Packets

US Patent:
20150365224, Dec 17, 2015
Filed:
Jun 17, 2014
Appl. No.:
14/306692
Inventors:
- Austin TX, US
STEVEN M. BOSZE - CEDAR PARK TX, US
KEVIN B. TRAYLOR - AUSTIN TX, US
JIANQIANG ZENG - AUSTIN TX, US
Assignee:
FREESCALE SEMICONDUCTOR, INC. - AUSTIN TX
International Classification:
H04L 7/00
H04L 1/00
H04B 3/54
Abstract:
A technique for frame synchronization in a communication system includes performing symbol correlation on received signal samples. A determination is made as to whether a magnitude of the symbol correlation is greater than a first threshold. In response to the magnitude of the symbol correlation being greater than the first threshold, an indication is provided that the received symbol is a valid symbol (e.g., a SYNCP symbol or SYNCM symbol). In response to the magnitude of the symbol correlation being less than the first threshold, an indication is provided that the received symbol is an indeterminate symbol (e.g., an invalid symbol or a SYNCM/2 symbol).

Frequency-Domain Symbol And Frame Synchronization In Multi-Carrier Systems

US Patent:
20140376540, Dec 25, 2014
Filed:
Jun 24, 2013
Appl. No.:
13/925023
Inventors:
Jianqiang Zeng - Austin TX, US
Steven M. Bosze - Cedar Park TX, US
Raja V. Tamma - Leander TX, US
Kevin B. Traylor - Austin TX, US
Khurram Waheed - Austin TX, US
International Classification:
H04W 56/00
US Classification:
370350
Abstract:
Methods and systems are disclosed for frequency-domain symbol and frame synchronization for multi-carrier communication systems. Received signals are sampled and converted into frequency components associated with subcarriers within the multi-carrier communication signals. Symbol synchronization is performed in the frequency domain by performing correlation(s) between frequency components of the received signal and frequency-domain synchronization symbol(s). After symbol synchronization, frame synchronization correlation is also performed in the frequency domain between frequency components of the received signal and frequency-domain synchronization symbol(s). The disclosed embodiments are particularly useful for symbol and frame synchronization in multi-carrier received signals for power line communication (PLC) systems and/or other harsh noisy communication environments.

Frequency-Domain Amplitude Normalization For Symbol Correlation In Multi-Carrier Systems

View page
US Patent:
20140376648, Dec 25, 2014
Filed:
Jun 24, 2013
Appl. No.:
13/924792
Inventors:
Jianqiang Zeng - Austin TX, US
Steven M. Bosze - Cedar Park TX, US
Raja V. Tamma - Leander TX, US
Kevin B. Traylor - Austin TX, US
International Classification:
H04L 27/26
US Classification:
375260
Abstract:
Methods and systems are disclosed for frequency-domain amplitude normalization for symbol correlation in multi-carrier communication systems. Digital samples associated with input signals received from a communication medium are processed using a Fast Fourier Transform (FFT) to generate complex frequency components. Each complex frequency component is normalized with respect to its amplitude, and the frequency-domain, amplitude-normalized frequency components are multiplied with frequency components for reference symbol(s) to generate frequency-domain correlation values. These frequency-domain correlation values are analyzed to determine if a correlation exists between the amplitude-normalized frequency components and the predetermined reference frequency components. A correlation detection output is then generated that indicates whether or not a symbol synchronization was achieved. The disclosed embodiments are particularly useful for symbol correlation in received signals for power line communication (PLC) systems.

Frequency-Domain Carrier Blanking For Multi-Carrier Systems

View page
US Patent:
20140376667, Dec 25, 2014
Filed:
Jun 24, 2013
Appl. No.:
13/924940
Inventors:
Jianqiang Zeng - Austin TX, US
Steven M. Bosze - Cedar Park TX, US
Raja V. Tamma - Leander TX, US
Kevin B. Traylor - Austin TX, US
International Classification:
H04L 27/26
US Classification:
375340
Abstract:
Methods and systems are disclosed for frequency-domain carrier blanking in multi-carrier communication systems. When excessive energy is detected in one or more subcarriers within a received symbol for multi-carrier communications, those subcarriers are blanked for subsequent demodulation in order to avoid corruption of the demodulated data. A conversion from time-domain digital samples to frequency-domain values using an FFT (Fast Fourier Transform) and a threshold detector are utilized to detect corrupted subcarriers. Further, this frequency-domain carrier blanking can be implemented dynamically on a symbol-by-symbol basis to further improve demodulation performance by reducing decoding errors. The disclosed embodiments are particularly useful for improving demodulation performance in power line communication (PLC) systems.

Frequency-Domain Frame Synchronization In Multi-Carrier Systems

US Patent:
20140376674, Dec 25, 2014
Filed:
Jun 24, 2013
Appl. No.:
13/924996
Inventors:
Jianqiang Zeng - Austin TX, US
Steven M. Bosze - Cedar Park TX, US
Raja V. Tamma - Leander TX, US
Kevin B. Traylor - Austin TX, US
International Classification:
H04L 27/26
US Classification:
375354
Abstract:
Methods and systems are disclosed for frequency-domain frame synchronization for multi-carrier communication systems. Received signals are sampled and converted into frequency domain components associated with subcarriers within the multi-carrier communication signals. A sliding-window correlation (e.g., two-dimensional sliding window) is applied to the received symbols represented in the frequency domain to detect frame boundaries for multi-carrier signals. The sliding-window frame synchronization can be applied by itself or can be applied in combination with one or more additional frame synchronization stages. The disclosed embodiments are particularly useful for frame synchronization of multi-carrier signals in PLC (power line communication) systems.
