Abstract

In this contribution, we propose a signal constellation for the the phase noise channel which does not require pilots thus increasing the effective information rate in a communication system. This constellation does not present rotational symmetry thus enabling decoding algorithms such as SPA, to converge without the use of pilots. We will provide Bit Error Rate (BER) simulations which show the superiority of this constellation over standard MPSK with pilots. Moreover, we will provide a method to analyze any arbitrary signal constellation and provide a figure of merit for its performance when iterative decoding algorithms are used.
