    • A receiver for a wireless communication device provides a dual path receiver receiving first and second protocol-agnostic, uncorrelated receive signals simultaneously. The dual path receiver generating first and second offset IF signals from the simultaneously received first and second protocol-agnostic, uncorrelated receive signals. The receiver utilizes at least one converter for converting the first and second offset IF signals into at least one serial synchronous interface (SSI) signal representing the spectrum at IF. At least one processor receives the at least one SSI signal and applies parallel processing paths to demodulate the at least one SSI signal into separate baseband signals. The processor provides interference detection of, and level control for, the first and second offset IF signals.

    • A genetic processor is used to process a plurality of baseband signals in a communication system. Signals received at an antenna array are processed to form chromosomes based on signal-to-interference-and-noise ratios. The chromosomes are further processed to determine a fitness of the chromosomes, and a weight set corresponding to a determined best fitness level is used to selectively process each signal to corresponding to each antennae of the array to increase the dynamic range of the receiver. In-phase, quadrature, amplitude and phase are signal characteristics that may be processed. In the transmit direction, the chromosomes are used to process the modulating signal supplied to each RF antenna, thus resulting in beamforming, the actual signal processing occurs digitally in the baseband spectrum. Chromosomes comprise a number of genes, or bits, based on the type of encoding scheme and the polarization, number and array grouping of antenna elements.
