The multi-user chirp modulation (M-CM) technique was introduced previously by the author as an efficient multiple-access technique using chirp modulation spread-spectrum signals. To further improve the performance of M-CM in multipath dispersive channels we suggest the application of frequency hopping (FH) to M-CM. The band of M-CM multiplexed signals is frequency-hopped within the allowed channel bandwidth. The application of FH is shown to highly improve the performance of M-CM signals in… CONTINUE READING
