Description: BPSK modulation with BER with and without OFDM
Here are the files for a OFDM modulation. Where in I have used a BPSK modulation and showed the decrease in BER with OFDM. This project was done as a course project under the Guidance of Dr. Dayalan Kasilingam, Umass Dartmouth.

Description: M=4的PSK通信系统进行蒙特卡罗仿真
仿真BPSK和4PSK调制信号在高斯信道下的性能，并与理论分析结果相比。
(1) 画出两条性能曲线，一条是根据理论平均错误概率画出，另一条是仿真曲线；
(2) 程序的基本流程：信源产生信息比特、调制、将调制信号送入信道(产生高斯白噪声的程序)、接收端检测、将检测结果与信源原始信息比较计算误符号率和误比特率；
(3) 在给定信噪比下，第二步需多次重复，以得到一个平均错误概率；
(4) 信噪比范围：BPSK(0dB – 10dB)，4PSK(0dB-14dB)，间隔是1dB 也可在BER=10-6左右终止。
(5) 信噪比计算 SNR=10log(Es/N0)=10log(REb/N0).

Description: 通过MATLAB软件；通过仿真得出性能曲线；从而比较bpsk的性能-The bit-error rate (BER) of binary phase-shift keying
in Rayleigh fading, using the Alamouti transmission scheme and
receiver selection diversity in the presence of channel-estimation
error, is studied. Closed-form expressions for the BER of log-likelihood
ratio selection, signal-to-noise ratio (SNR) selection, switchand-
stay combining selection, and maximum ratio combining are
derived in terms of the SNR and the cross-correlation coefficient
of the channel gain and its corrupted estimate. Two new selection
schemes, space–time sum-of-squares combining selection diversity
and space–time sum-of-magnitudes selection diversity, are
proposed and proven to provide almost the same performance as
SNR selection, but with much simpler implementations. The effects
of channel-

Description: C program to calculate the BER performance of BPSK modulation in an AWGN channel. The program takes the file "BPSK" containing voltage levels and passes it in an AWGN channel with a given SNR. The received message is then Hard decision decoded and the bit error rate is calculated.
The BER over different SNR is calculated. THe output values can be used to draw a BER vs SNR(dB) curve.

Description: The simplest channel which we use in ideal case is AWGN channel and everyone knows that before starting siluation on the other part of the system we must simulate the AWGN channel.this is AWGN channel with a BPSK signal going through it and finally we detect the signal and plot BER vs SNR to compair with the theory.
