I want a freelancer to do Matlab coding for OFDM System. These codes are also available online so freelancer can use the existing codes. I just want the below two simulations to work and get the output in Matlab.
Simulation 1: Write matlab code to Simulate OFDM system with different modulation scheme like (BPSK , QPSK and (16 , 64) QAM) and the transmitted signal pass through mutlipath rayleigh channel (fast fading) which the channel has (multi path and its delay and its gain and the Doppler frequency). In the receiver, use adaptive algorithms (RLS , LMS and Bidirectional LMS) to estimate the channel and then detect the transmitted data.
Simulation 2: Design normal OFDM system which include ordinary training sequence (pilot) in front of each block of data to be transmitted, with different modulation scheme like (BPSK , QPSK and (16 , 64) QAM) and the transmitted signal pass through mutlipath rayleigh channel (fast fading) which the channel has (multipath and its delay and its gain and the Doppler frequency). In the receiver used ( RLS , LMS and Bidirectional LMS) adaptive algorithm to estimate the channel and then detect the transmitted data.
All you need to do is to make the Matlab program to simulate both conditions and obtain the results in the form of graphs. The freelancer can use the existing available Matlab code and make a two .m files such as simulation1.m and simulation2.m
I attached a file with this message, it is a simple example about what i want. you can see from the example i sent data with 16QAM modulation through Rayleigh Channel and processed it by RLS algorithm (to estimate the effect of the channel which is the (w = [login to view URL])) and you can see from figure1 and figure of the Impulse responses of the channel (time varying channel) I succeed to tracking the channel and get it's coefficients (the effect). but i do not know what i must do to get the clean data or how process the received data (distorted data (re)) by using the Coefficients (w) which I got or any another method and then plot the learning curve and calculate the bit error rate, If I succeed to get the clean data then I will apply this example on OFDM system and use the standard numbers in calculation.
