Differentially coherent TC-PSK with subset dilation
Abstract
The implications of deviating from the PSK transmit constellations for differential detection are explored. By introducing subset dilation, the free distance of the shortest error paths is increased. Analysis based on asymptotic coding gains and simulation results indicate that, by exploiting the trellis structure, moderate bit error rate improvements are possible without increasing the receiver complexity.
