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 0.1dB. By this approach, computation burden and power consuming can be reduced remarkably.
