Low-complexity iterative method of equalization for single carrier with cyclic prefix in doubly selective channels
TLDR
In this paper, we propose a time-domain low-complexity iterative algorithm to compensate for the effects of time selectivity of the channel that exploits the sparsity present in the channel convolution matrix. Expand
