| 摘 要： | 基于最小错误概率准则，设计了非正弦时域正交调制信号的解调模型，理论分析了加性白色高斯噪声(additive white Gaussian noise, AWGN)信道下通信系统的差错性能。结果表明，非正弦时域正交调制可达到与正交频分复用(orthogonal frequency division multiplexing, OFDM)相同的差错性能，且其单位频带利用率的提升速度优于OFDM。复杂度分析结果表明，其解调复杂度虽然高于OFDM，但仍具有硬件可实现性，可用于长波至超短波的通信频段。

| Abstract: | Based on minimum error principle,a demodulation model is proposed for nonsinusoidal orthogonal modulation signals.The error rate is analyzed theoretically at additive white Gaussian noise(AWGN) for this communication system.The result shows that the error rate performance is the same with orthogonal frequency division multiplexing(OFDM),and the bandwidth efficiency can be fast improved and is better than OFDM.The complexity degree is analyzed for the demodulation model,which is higher than OFDM,but the modu... |
