Abstract
Simple two channel receivers for 32-PSK and 64-PSK modulated signals have
been proposed which allow digital data (namely bits), to be recovered directly instead
of the traditional approach of symbol detection followed by symbol to bit mappings.
This allows for binary rather than M-ary receiver decisions, reduces the amount of
signal processing operations and permits parallel recovery of the bits. The noise
performance of these receivers quantified by the Bit Error Rate (BER) assuming an
Additive White Gaussion Noise interference model is evaluated as a function of E^/N^,
the signal to noise ratio, and transmitted phase angles of the signals. The performance
results of the direct bit detection receivers (DBDR) when compared to that of
conventional phase measurement receivers demonstrate that DBDR's are optimum in
BER sense. The simplicity of the receiver implementations and the BER of the
delivered data make DBDR's attractive for high speed, spectrally efficient digital
communication systems.
