Fast multiple-antenna differential decoding.

We present an algorithm based on lattice reduction for the fast decoding of diagonal differential modulation across multiple antenna. While the complexity of the maximum-likelihood (ML) algorithm is exponential both in the number of antenna and the rate, the complexity of our approximate lattice alg...
