We demonstrate the feasibility of a digital beam forming (DBF) and beam space CMA (Constant Modulus Algorithm) adaptive array antenna by implementing a digital signal processor (DSP) in ASICs using field programmable gate arrays (FPGA), this DBF can synthesize 16 multi-beams and eliminate interference signals by CMA adaptive processing. The whole function was implemented in 10 DSPs about 127,000 equivalent gates. Simple experimental results have confirmed the basic function of the DBF and BSCMA adaptive array antenna
