摘要: We analyze two-user single-antenna fading interference channels with perfect receive channel state information (CSI) and no transmit CSI. compute the diversity-multiplexing tradeoff (DMT) region of a fixed-power-split Han Kobayashi (HK)-type superposition coding scheme provide design criteria for corresponding codes. demonstrate that this is DMT-optimal under moderate, strong, very strong by showing it achieves DMT outer bound we derive. Further, interference, show joint decoder "decouples" channel, i.e., from perspective, possible to as if interfering user were not present. In addition, that, decoding while treating intended signal noise, subtracting result out, then desired signal, process known "stripping", optimal region. Our proofs are constructive in sense code achieving DMT-optimality (in cases where can it) provided.
