A Bandwidth Efficient Constant Envelope Modulation with Reed-Solomon Coding
Douglas J. Hermes, Frank E. Kragh · 2007
This paper presents Reed-Solomon (RS) coding applied to an innovative, constant envelope modulation technique that was originally developed by Resnikoff and Tigerman [1]. The general waveform and phaseform are presented as-well-as probability of bit error and symbol error expressions for uncoded binary and uncoded M-ary modulation, respectively. Bit error performance analysis is presented for the case of RS coded waveforms when the modulation symbol size (M) is less than the RS coded symbol size (Q). In addition, upper and lower performance bounds are derived for RS coded waveforms for M less than Q. Performance analysis curves are presented for the M = 8 and Q = 64 case. Finally, simulation results are also presented for the M = 8 and Q = 64 case that strongly agree with analysis.
