Abstract :
We present the development of a simulation model and for a conceptual DS-CDMA system and simulation baseband models for the least-square despread respread multitarget array (LS-DRMTA) algorithm with two, four and six antenna elements in the Matlab/Simulink environment. The models are used to compare the performance of single and multiple adaptive antenna systems in an AWGN channel. The simulation models show the clear advantage of multiple antenna systems and represent a first step towards their implementation on an FPGA platform.
