Abstract :
This paper discusses two basic structures of AGC (automatic gain control) and their corresponding hardware implementations in FPGA (field programmable gate array). Some area-efficient algorithms are developed and adopted. A performance comparison between the two implementations through fixed-point simulation of MATLAB is presented.
