Abstract: In order to generate multiple-access signals, each transmitter transmits information by using all or a part of channel resources. The signal of each transmitter is mapped to an OFDM time-frequency resource space as a trellis modulation path. A mobile communication system maps trellis modulation paths of a plurality of transmitters to the same resource space. In order to effectively detect and distinguish signals of a plurality of transmitters transmitted through the same channel resource space, a receiver uses a message passing method between symbols and a path connection method. The receiver uses a state space expansion method, a backward pre-decoding method, and a successive interference cancellation method to more efficiently reconstruct a discovery signal.
Abstract translation: 为了产生多址信号，每个发射机通过使用全部或部分信道资源来发送信息。 每个发射机的信号被映射到OFDM时频资源空间作为网格调制路径。 移动通信系统将多个发射机的网格调制路径映射到相同的资源空间。 为了有效地检测和区分通过相同信道资源空间发送的多个发射机的信号，接收机使用符号之间的消息传递方法和路径连接方法。 接收机使用状态空间扩展方法，反向预解码方法和连续干扰消除方法来更有效地重构发现信号。
