Sliding window superposition coding in two user MIMO interference channel

Abstract

We design a transmission scheme which uses sliding window superposition coding in multiple input multiple output(MIMO) environment. The performance of this scheme is compared with two simultaneous decoding schemes:IAD and IASD. To compare these schemes, we calculate the frame error rate. We observed that improved gain from our proposed encoding process cannot mitigate the loss of using successive interference cancellation instead of joint maximum likelihood decoding. So we strengthen this scheme by using the joint detection with losing the advantage of low complexity. We concluded that the modified scheme achieves better performance than the other simultaneous decoding schemes.
