Description: MATLAB program for OFDM generation and reception
This is a simple MCM communications system. The code is pretty self-explanatory. Here I have not used the cyclic prefix.
Transmitter End:
1. Generate random serial data with M symbols (RANDSRC will do this)
2. Perform modulation (4-PSK = QPSK for now)
3. Serial to parallel
4. IFFT
5. Parallel to serial
Receiver end
Just opposite of transmitter end.

Description: papr to differenrt number of subcarrier:
we put N = 256,512,1024 and show the output ofp ccdf with papr when we use QPSK modulation.
The PAPR ratio is a measure of the dynamic range in OFDM signals. Thus high
PAPR induces a high dynamic range which describes high variability in the
signal range.
complex data sequences are input to the IDFT of an OFDM transmitter
then at the output of the IDFT, real and imaginary parts are obtained. Platform: |

Description: 实现基于STBC的MIMO_OFDM通信系统在不同信噪比情况下接收端的误比特率的仿真。发射端包括基于基带调制、空时编码、导频插入、IFFT、串并合并以及添加循环前缀;接收端包括去除循环前缀、取出导频估计信道、FFT运算以及并串合并,空时解码等。仿真中采用QPSK、空时编码采用4*3的复正交空时编码矩阵。OFDM子载波数为100,每个子载波传输66个符号,每个符号2比特。IFFT长度为512个符号。发射天线为3个接收天线为2个。(The BER simulation of MIMO_OFDM communication system based on STBC under different SNR is realized. The transmitter includes baseband modulation, space-time coding, pilot insertion, IFFT, serial-parallel combination and adding cyclic prefix; the receiver includes removing cyclic prefix, extracting pilot estimation channel, FFT operation, parallel-serial combination, space-time decoding, etc. The complex orthogonal space-time coding matrix is used in QPSK and space time coding in 4*3. The number of OFDM subcarriers is 100, and each subcarrier transfers 66 symbols with 2 bits per symbol. IFFT is 512 symbols in length. The transmitting antenna is 3 receiving antennas, 2.)
