TDPC 编码器

代码说明：

This file simulates a two-dimensional parity check encoder.  Consider a wireless communication scheme which is designed to convey messages between a transmitter  and a receiver over a wireless channel. Suppose that each message is a row vector x comprising k number  of symbols. Each symbol has an integer value in the range 0 to (M − 1), where M is known as the radix of  the symbols. For example, the message vector x = [2, 0, 1, 1, 3, 2] comprises k = 6 symbols, having a radix  of M = 4.
