256QAM的调制解调matlab源代码(256QAM modulation and demodulation matlab source code)

该程序完成一个16电平PAM数字通信系统的仿真，并测量了它的误码率。首先产生信息符号序列，该序列被当做4个信息比特一组，将16组符号映射到16个信息幅度。检测器计算距离，输出与真正传输的信息符号序列作比较，然后将差错计数。( This procedure completes a 16 level PAM digital communication system s simulation, and has surveyed its error rate. First has the message digit sequence, this sequence is treated as a 4 information bit group, maps 16 class symbols to 16 information scopes. The detector estimated range, the output and the true transmission s message digit sequence does compares, then counts the mistake. )

Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne, CDMA2000 (the 3G evolution of cdmaOne) and WCDMA (the 3G standard used by GSM carriers), which are often referred to as simply CDMA, and use CDMA as an underlying channel access method.
