CMMB_C
- 因为只是仿真物理层的性能，所以只对一个RS交织块进行处理，RS块的大小可为协议中RS的字节交织模式中的规定的三种交织深度。其它调制参数都可选，如RS码率，LDPC码率等。程序最后的输出即为经过CMMB发射调制的OFDM基带数据。-Because it is only the physical layer performance simulation, only the interleaved block for processing an RS, RS block size for the pr
OFDM
- OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部
