Z mac is the medium access control which is the combination of both TDMA and CDMA

该例程内容丰富，包括从基本的bpsk,qpsk,qam到实际的ofdm系统，cdma链路，mac层仿真分析，对OFDM信道建模，包括普通IDFT算法和IFFT快速算法，基于OFDM体制的调制和解调程序，降低OFDM系统PAPR的pts算法的仿真程序，完整的OFDM链路程序并作了较为具体的解析-The routines cover a wide range from basic bpsk, qpsk, qam to the actual ofdm systems, cdma link, mac l

his paper proposes a novel multichannel medium access control(MAC)protocol based on CDMA that improves network performance and reduces collision probabifity in wireless ad hoc networks．
