Software radio research of spread spectrum communication system

Developing status of software radio is introduced. The configuration of software radio in direct sequence spread spectrum communication system is realized, which are composed of the configurations of both transmitter and receiver. The capture and stealth problems of extended coding phase are researched. At last, the working status of BPSK and QPSK modulated system is emulated using DSP emulator CCS2.0, and the result is satisfying.
