Polar-coded perturbation sphere decoding algorithm over Rayleigh fading channel

A perturbation sphere decoding algorithm for control channels with small payload size is proposed in this paper. When a codeword fails the cyclic redundancy check (CRC), the algorithm performs a perturbation operation by adding noise to the codeword and achieves a new received sequence. Subsequently...
