摘要: In this paper, the tradeoff between diversity and multiplexing gains in two-user quasi-static Raleigh fading Interference Channel (IC) is derived. Under short-term average power constraint for delay limited communication, we show that only a partial State Information at Transmitter (CSIT) enough to achieve optimum Diversity-Multiplexing Tradeoff (DMT) IC. We develop coding scheme At low rate region, results one-level Gaussian code independent of channel condition. high result can be or two-level codes depending on CSIT. The state information each gain represented by one bit corresponding its absolute value. assume all available two transmit sides. optimality proposed established deriving an outer bound, which coincides with achieved DMT.
