Abstract:
A combined Adaptive Filtering, Adaptive Antenna Array and Adaptive Locally-Optimum Detection (AF-AAA-ALOD) system comprising:a plurality of antenna elements, including a reference antenna element and a plurality of auxiliary antenna elements for receiving respective input signals; a master AF processing block configured for receiving the input signal received by the reference antenna element and outputting an output signal and filter parameters; a plurality of slave AF processing blocks each configured for receiving a corresponding input signal from the respective input signals and the filter parameters outputted by the master AF processing block and outputting an output signal; a plurality of weighting blocks each configured for receiving a corresponding output signal outputted by a respective slave AF processing block of the plurality of slave AF processing blocks, multiplying the corresponding output signal using a respective weight from a plurality of weights to generate a weighted output signal, and outputting the weighted output signal; a summation block configured for receiving the output signal outputted by the master AF processing block and the weighted output signals and outputting an output signal; an ALOD processing block configured for receiving the output signal from the summation block and at least locally-optimum detection processing the received output signal to output a system output signal and at least one error feedback signal; and a weighting block configured for receiving the at least one error feedback signal and generating the plurality of weights.
