摘要: We study the degrees of freedom characterization wireless X networks, i.e. networks M distributed single antenna transmitters and N receivers where every transmitter has an independent message to receiver. provide outerbound on capacity region within o(log(SNR)). If channel co-efficients are time-varying/frequency selective, we show that total number is equal MN/M+N-1 using a coding scheme based idea interference alignment.
