A spatial processing stereo system (“SPSS”) that receives audio signals and a limited number of user input parameters associated with the spatial attributes of a room, such as “room size”, “stage distance”, and “stage width”. The input parameters are used to define a listening room and generate coefficients, room impulse responses, and scaling factors that are used generate additional surround signals.

An antenna system includes N movable antenna elements configured to generate concurrently M receiving beams pointing respectively at M satellites radiating in a common frequency band, N and M being integers and N≥M≥2. A beam forming system is coupled to the N movable antenna elements and configured to shape the M receiving beams using weights inputted from a beam controller. The beam controller optimizes the M receiving beams by computing spatial displacements to spatially reposition the N movable antenna elements relative to each other, using an iterative optimization processing to satisfy a plurality of constraints concurrently. A position driver system spatially re-positions the N movable antenna elements in accordance to the spatial displacements inputted from the beam controller.

An antenna system comprises: multiple antenna elements; and multiple beam forming networks configured to produce radiation patterns for both receiving and transmission functions configured to be optimized by re-positioning said antenna elements, wherein said beam forming networks comprise a receiving beam forming network configured to combine multiple first inputs from said antenna elements into at least a first output, and a transmission beam forming network configured to divide a second input into multiple second outputs to said antenna elements.
