The Procedure of Multi-Criteria Synthesis of DSSS Radio Signals to Adapt Prospective Wireless Communication Systems to the Action of NarrowBand Interference

摘要

Synthesis procedure for multi-position DSSS signals to adapt promising wireless communication systems to the action of narrow-band interference based on methods of code sequences ensemble multi-criteria optimization is proposed. It is shown that the signals obtained as the result of synthesis provide the gain in noise immunity of up to 5 dB (compared to QPSK signals with DSSS by supplemented maximum length sequence) with improved cross-correlation characteristics that indirectly determine the sensitivity to errors of clock synchronization system.
