GLRT-Optimal Noncoherent Lattice Decoding

Differential Lattice Decoding in Noncoherent MIMO Communication

We present improved differential lattice decoding (DLD) for multi-antenna differential modulation by exploiting both basis reduction and sphere decoding. The extra complexity of DLD is shown to be worthwhile in terms of the obtained performance gain over Clarkson et al.’s decoding scheme. With roughly another fold of complexity of basis reduction, DLD augmented by a local search practically at...

Noncoherent turbo decoding

In this paper, we propose a new Turbo code noncoherent detection scheme based on a novel a-priori probability processor (APP). Using this method, many turbo encoders can be used without a change in the code or in the modulation, and without a significant change in the structure of the iterative decoder. Simulation results of this method are presented for various phase noise levels. We show a de...

Noncoherent iterative (turbo) decoding

Recently, noncoherent sequence detection schemes for coded linear and continuous phase modulations have been proposed, which deliver hard decisions by means of a Viterbi algorithm. The current trend in digital transmission systems toward iterative decoding algorithms motivates an extension of these schemes. In this paper, we propose two noncoherent soft-output decoding algorithms. The first sol...
