A method of producing a fuel composition from a bio-oil feedstock is provided, wherein the bio-oil feedstock is subjected to a step of oil extraction to produce a bio-oil and deoiled residue. At least a portion of the deoiled residue is gasified to produce a hydrogen-containing gas. The bio-oil is subjected to an upgrading process to ultimately produce a fuel composition. At least a part of the hydrogen-containing gas produced in the gasification of deoiled residue is used in the upgrading process of producing a fuel composition. The upgrading process, which can involve hydro-treating, hydroisomerization and at least one separation step, produces light hydrocarbons in addition to the product fuel composition. The light hydrocarbons can be used in the gasification operation, e. g. , to reduce tar formation.

Providing for secondary synchronization encoding utilizing a primary synchronization channel (P-SCH)-related scrambling code is described herein. Scrambled secondary synchronization codes (SSCs) can be assigned to multiple base stations of a radio access network (RAN). By way of example, PSC-based scrambling codes can be created from a plurality of M-sequences generated from a common polynomial expression. Further, an SSC codebook is provided that selects sequence pairs of a sequence matrix for generating SSCs. Selection can be based on transmission characteristics of resulting SSCs, providing reduced interference in planned, semi-planned and/or unplanned mobile deployments.

A system for removing sulfur from a gaseous stream includes (a) a reaction bed for receiving the gaseous stream and for reacting sulfur dioxide and at least some of the hydrogen sulfide of the gaseous stream into elemental sulfur to provide an elemental sulfur stream and a first product stream; and (b) a circulating fluidized bed comprising (i) a first region for receiving the first product stream and using a sulfur adsorption material to adsorb and remove any remaining hydrogen sulfide from the first product stream to generate saturated sulfur adsorption material and a second product stream substantially free of sulfur; and (ii) a second region for receiving a regeneration stream and for using the regeneration stream to regenerate the saturated sulfur adsorption material and to generate the sulfur dioxide.

Systems and methods are provided to generate a set of synchronization channel sequences that optimize time and frequency acquisition. A set of root indices of Zadoff-Chu sequences in a first domain (e. g. , time domain) that optimize a performance metric or merit factor are identified. An optimal index is determined that also optimizes a performance metric in a reciprocal domain (e. g. , frequency domain). Optimal indices satisfy a centro-symmetric relationship with respect to a half-value of sequence length: When 1 is an optimal index, N−1 is also an optimal root index. For sequences of length Q=N, a base sequence generated with an optimal sequence can be utilized to generate at least two disparate optimal sequences through sign-flip, conjugation, and periodic modulation operations.

Efficient apparatus and method for Zadoff-Chu (“Chu”) sequence generation avoids additional processing and hardware complexity of conventional quadratic generating formula followed by Discrete Fourier Transform (DFT) with a reference signal generator that produces both a Zadoff-Chu sequence and its DFT. In the wireless communication system (e. g. , Long Term Evolution (LTE) system), Chu sequences are extensively used, especially in the uplink (UL). Because of the single carrier operating mode, transmitting a Chu sequence in principle involves a succession of generating that sequence, performing a DFT operation and then an IFFT operation. Assuming that the sequence length is N, the initial sequence generation requires 2N multiplications and the DFT requires more than N log 2(N) multiplications. Given the frequent processing of Chu sequences, this would represent a complexity burden. The invention makes it possible to perform the sequence generation and DFT steps without any multiplication operation, except for possibly calculating certain initial parameters.

Decision metrics used to decode wireless communication payloads are combined for successive frames to improve decoding of the later received frames. A bitwise payload difference between successive frames is encoded in the same manner the payloads are encoded. Decision metrics determined for the earlier received frame are combined with the encoded payload difference to generate adjusted decision metrics. The adjusted decision metrics are combined with decision metrics determined for the later received frame. The combined decision metrics are decoded to generate a payload for the later received frame. If the decoding is not successful the combined decision metrics are carried forward and the process is repeated based on the payload difference between the following frames.

Certain embodiments of the present disclosure propose two efficient designs for a control channel in a Coordinated Multi-Point (CoMP) system. The proposed designs enable a user equipment (UE) to transmit acknowledgement (ACK) and negative acknowledgement (NACK) signals to one or more access points (APs) upon receiving transmissions from them.
