由于大多数部署的无线网络的分层结构和异构性，使用相同通信资源（例如相同频带和时隙）的多个数据传输可能发生在相同区域中。因此，干扰对于受干扰信号的解码变得至关重要。已经存在许多处理干扰的技术，这些技术可以在发射机（Tx）或接收机（Rx）或两者处实现，以支持同时的多用户传输。我们专注于接收设计在多个接入信道（MAC），多个Tx发送数据到一个共同的Rx同时。通过利用干扰信号之间的建设性/破坏性的相互作用，我们提出了一个Rx结构的基础上的干扰组合（ICom），结合迫零（ZF）和连续干扰消除（SIC）。此外，通过利用期望信号和干扰之间的关系，接收模式自适应被用来进一步提高所提出的接收机制的性能。所提出的Rx结构不需要在Tx侧进行协调，并且可以以适度的处理成本显著减少接收天线的数量。基于ICom的接收被证明不仅能够在严格的延迟约束下显著提高系统频谱效率（SE），而且能够在接收天线的要求和信号处理复杂度之间进行灵活的权衡，从而促进其实现和部署。
Due to the hierarchical structure and heterogeneity of most deployed wireless networks, multiple data transmissions using the same communication resource, such as same frequency band and time slot, are likely to occur in the same area. Hence, interference becomes critical to the decoding of interfered signals. There have already been numerous techniques dealing with interferences that can be implemented either at the transmitter (Tx) or the receiver (Rx) or both, to support simultaneous multi-user transmissions. We focus on the reception design in multiple access channels (MACs) where multiple Txs send data to a common Rx simultaneously. By exploiting the constructive/destructive interactions among interfering signals, we propose a Rx structure based on interference combination (ICom) that incorporates zero-forcing (ZF) and successive interference cancellation (SIC). In addition, by exploiting the relationship between the desired signal and interference, reception mode adaptation is employed to further improve the performance of the proposed reception mechanism. The proposed Rx structure does not require coordination at the Tx side and can significantly reduce the number of receiving antennas at a moderate processing cost. The ICom-based reception is shown to be able to make not only a significant improvement of system spectral efficiency (SE) under stringent latency constraints, but also a flexible tradeoff between the requirements of receive antennas and signal processing complexity, thus facilitating its implementation and deployment.
