Abstract:
The procedure for fast multi-criteria synthesis of four-position radio signal is proposed. The vector of criteria for the radio signal synthesis includes elements for increase: AWGN and narrow-band interference immunity, as well as power and bandwidth efficiency. This procedure is based on determination of functional relationship between signal set samples and central frequency of narrow-band interference. The adequacy of the procedure is confirmed for deviation of external parameters from values those are approximated by the functional relationship. It is shown that the procedure increase narrow-band interference immunity up to 15 dB compared to QPSK signal.
