摘要： The receiving device receives a transmitted signal from a transmitting device by dividing by N the spectrum of a signal to be transmitted and performing spectrum editing to reduce its occupied bands. The receiving device generates a first decoded signal by error-correcting and decoding this received signal in the bandwidth of the signal to be transmitted, and generates a transmission replica signal from this first decoded signal and divides by N the spectrum of this transmission replica signal to generate N sub-replicas. The receiving device generates a compensated received signal by restoring the spectrum of the signal to be transmitted from the transmitting device using the N sub-replicas and the received signal, and decodes this compensated received signal to generate a second decoded signal.
摘要翻译： 接收装置通过将N发送的信号的频谱除以发送装置的发送信号，进行频谱编辑，以减少占用频带。 接收装置通过在要发送的信号的带宽中对该接收信号进行纠错和解码来生成第一解码信号，并从该第一解码信号生成发送复制信号，并将该发送复制信号的频谱除以N， 生成N个副副本。 接收装置通过使用N个副副本和接收信号来恢复从发送装置发送的信号的频谱来产生经补偿的接收信号，并对该经补偿的接收信号进行解码，生成第二解码信号。
