Q_DSSS
- 直扩码分多址DS-CDMA是利用高速的WALSH正交码序列作为地址码,与多用户信息数据相乘得到信息数据的直接扩频信号,再经过BPSK调制后发送出去,经过AWGN无线信道的传输后,在接收端与本地产生的地址码进行相关检测,从中将地址码与本地码一致的用户数据选出,把不一致的用户数据删除。-DS-CDMA DS-CDMA is the use of high-speed WALSH orthogonal code sequences as address code, with multi-user in
DS_BPSK_TX
- This m file generates a DS BPSK transmitter(spread spectrum) using PRBS s which are modulus 2 added(exclusive ored)with the message and then used to BPSK modulate a carrier.
