摘要 为了降低接收机功耗,提出一种基于插值的单倍采样接收机架构.性能分析显示,在具备成形滤波器的情况下,此构架仅以不足0.1dB的损失为代价,将抗干扰计算量降低了一半,从而极大地降低了接收机计算负担和整体功耗. DS-SS is widely used in LEO satellite communication. Since jamming exists in UHF/VHF wave band, which is commonly selected by LEO communication system, anti-jamming module is necessary in receivers. To control the power consuming, an interpolation-based one-sample-per-chip receiver architecture is developed. Performance analyses show that this architecture cuts off half of anti-jamming module computation burden at the cost of the SNR lose less than 0. 1 dB. By this approach, computation burden and power consuming can be reduced remarkably.
