matlab程序源代码，能够正确实现，最近邻分类(matlab program source code, to be able to correctly implement the nearest neighbor classifier)

The software is capable to simulate space time code [1] for QPSK modulation using different number of state. Examples of generator matrix up to 256 stetes are provided. Variable signal to noise ratio (SNR) might be applied to produce bit error rate (BER) or frame error rate (FER) curves.(The software is capable to simulate space time code [1] for QPSK modulation using different number of state.
