Abstract：RAKE reception is an anti-multipath technique suitable for spread spectrum communication and frequency selective fading channels.This paper analyzes the problems to be optimized when the traditional RAKE receiving technology is applied in parallel combined spread spectrum scattering(PCSS-SC)communication system,and combines the channel multipath fading analysis and simulation model to explain that the system is suitable for the RAKE receiving design requirements.In order to improve the severe multipath fading of the scattering channel,an active RAKE reception model based on pilot sequence is proposed based on the characteristics of the parallel system of PCSS system.The simulation results show that the model can be adapted to the PCSS-SC communication environment while improving the traditional RAKE receiving technology,effectively reducing the bit error rate of the system.
