摘要 针对普通的Chirp-BOK调制效率不高的问题,设计了基于Chirp-BOK-DQPSK调制的超宽带(UWB)无线通信系统,推导与验证了该系统在AWGN信道下的误比特率,分析了该系统在多径环境下存在较大码间干扰的原因。最后通过仿真分析比较了该系统和Chirp-BOK-UWB系统、Chirp-BOK-DBPSK-UWB系统在IEEE 802.15 SG4a给出的CM1和CM7信道下的性能。仿真结果表明,该系统在牺牲一定误码率性能的情况下,能有效提高传输速率。 In order to solve the low efficiency problem of Chirp-BOK modulation,this paper proposed UWB wireless communication system based on Chirp-BOK-DQPSK modulation.Analyzed and validated the BER performance in AWGN channel,and investigated the reason of inter-symbol interference in multipath channel.Simulation had been done to compare the performance of Chirp-BOK-DQPSK-UWB with Chirp-BOK-UWB and Chirp-BOK-DBPSK-UWB in IEEE 802.15SG4a CM1 and CM7 channel.The simulation results show that the system can efficiently improve the transmission rate with some reduction of the BER performance.
