Abstract :
For a DS/FFH spectrum spread system, DAGC(Digital AGC) diversity combining is investigated. The performance of DAGC is evaluated under the case of partial-band jamming plus AWGN. Performances of several widely-used methods of diversity combining are compared with DAGC. The coherent DS/FFH system with DAGC has been implemented in a FPGA circuit, tested and verified to be effective for practical realizations.
