说明：  ofdm信道估计，采用了LS算法，DFT进行插值(OFDM channel estimation adopts LS algorithm and DFT interpolation)

This program simulates the bit-error-rate (BER) performance of OSTBC with L=4 antennas over the frequency flat Rayleigh block fading channel The code is developed for real orthogonal design, code rate 1/2 modulation- 16 QAM with gray coding resulting in 2 bits/sec/Hz.

BPSK调制方式AWGN信道的理论误码率、仿真误码率以及瑞利信道下的理论值和仿真误码率(Theoretical BER of BPSK modulation AWGN channel BER simulation and theoretical value of the Rayleigh channel simulation error rate)

说明：  在AM信号中，载波分量并不携带信息，仍占据大部分功率，如果抑制载波分量的发送，就能够提高功率效率，这就抑制载波双边带调制DSB-SC（Double Side Band with Suppressed Carrier），简称双边带调制（DSB）。(In AM signal, the carrier component does not carry information and still occupies most of the power. If the transmission of the carrier component is suppressed, the power efficiency can be improved. This is called double side band with suppressed carrier (DSB for short).)

Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assuming BPSK. Brute force Monte Carlo approach is unsatisfactory (takes too long) to find the BER curve. The computation uses a quasi-analytic (QA) technique that relies on the estimation (approximate one) of the information-bits Weight Enumerating Function (WEF) using A simulation of the convolutional encoder. Once the WEF is estimated, the analytic formula for the BER is used.(Computes BER v EbNo curve for convolutional encoding/soft decision Viterbi decoding scheme assuming BPSK.
