NONCOHERENT EQUICORRELATED MODULATION SIGNALS

摘要

This paper investigates the M-ary multiple-pulse equicorrelated modulation (ECM) signals which enable noncoherent block detection. The multiple-pulse ECM signals constructed from various time-limited and band-limited basis waveform sets are also explored for spectral performance characteristics. Tight upper and approximate bounds are derived and verified by simulation to evaluate the bit and symbol error probability characteristics of the developed ECM block receiver. It is analytically shown that the noncoherent M-ary ECM block receiver with a small-sized block-length performs comparably with the ideal coherent M-ary simplex receiver when the pairwise signal correlation is appropriately chosen.
