| 摘 要： | 针对跳频通信系统，提出一种非相干的，高频带利用率的调制方案。该方案是以多进制ASK和正交频分复用（OFDM）相结合。这个方案能使所需的数据带宽最小。对固定的扩频带宽来说，用户使用的频率通道数量大大增加。针对附加了高斯白噪声的FH—OFDM-MASK系统提出了简单而又精确的误比特率表达式。

| Abstract: | A noncoherent,bandwidth-efficient modulation scheme is proposed for frequency-hopping communication system.The proposed scheme is a combination of noncoherent M-ary amplitude-shift keying(NMASK) and orthogonal frequency-division multiplexing(OFDM).The using of this scheme will minimize the required data bandwidth.The number of frequency slots available to the users will be increased significantly for the fixed spread-spectrum bandwidth(BWSS).The simple and accurate bit error rate expressions have been derived for FH-OFDM-MASK in additive white Gaussian noise channels. |
