Adaptive array processing unit based on direct data domain least square approach using conjugate gradient method

This paper presents the design of an adaptive array processing unit based on direct data domain least square approach using conjugate gradient method. The unit was applied for operation in the adaptive antenna scenario. The efficient architecture for FPGA implementation using fixed-point operation is present. The simulations are shown to evaluate the performance of the proposed adaptive processing unit. Moreover, simulation results obtained from the unit using fixed-point operations also show a good agreement with the unit using floating point operations.
