Abstract :
We propose a novel hybrid automatic repeat-request (HARQ) scheme for non-orthogonal space-time block codes based on BCH and Reed Solomon codes. We use list decoding techniques to significantly reduce the decoding complexity. We obtain significant gains in terms of dropped packet rate and throughput spectral efficiency at the cost of increased complexity.
