We demonstrate a feasibility of a Beam Space CMA (Constant Modulus Algorithm) Adaptive array antenna by implementing a Digital Signal Processor (DSP) in ASICs using field programmable gate arrays (FPGA). The DSP can synthesize 16 multibeams and eliminate interference signals by CMA adaptive processing. The whole function was implemented in about 127,000 equivalent gates. Simple experimental results in a radio anechoic chamber have confirmed the basic function of BSCMA adaptive array antenna.
