In mobile communications a multi-path signal is received in the receptor. Environment interferences make the signal increase or decrease according to its phase. This program allows you to learn how frequency and speed modify the signal pattern at the receiver.

is this simulation suitable for the Distributed Antenna System?
i need to do the similar simulation for my final year project.
anyone can help me??

could you provide code for
producing a sequence of N independent Rayleigh fading samples, with mean-square
value equal to one

it is very good.

This is good simulation .if possible ,i request you to post "DS CDMA simulation in fadind channel".THANK YOU!

This piece of code is based on deterninistic models approximate the Gaussian processes, which is Proposed by Jakes(Microwave mobile communications),and also described in Yunxin Li(Simulation of Independent rayleigh faders), and P. Dent's paper(Jakes fading model revisited).

Statistical models need much more work,such as gerneration of white Gaussian random processes , fir(or iir)filters disign and filtering, etc.
But it dose work!

Implements Jakes Fading Model which is well known to have undesired correlations for multi-path independent faders

it is the most simple jakes model. Very old. It has WSS, cross correlation problems

hi,could you please send me more about the simulation(explained in more detail) thanks

hi, i would be thankful, if u could provide me with the code to simulate "rayleigh flat faiding" fast, slow, and block on matlab.

I wanted to know if these files is really needed, as far as I know, simulink has a "Rayleigh Fading channel" Block. I want to make sure that this block of simulink works correctly?

hi, i hope you give me more about the the simulation using matlab. thanks lot.

hallo,
how can I use this file,
if S(t) is the transmitted signal,
and R(t) is the received signa,

your rayleigh distribution plot is incorrect

It's an good approach to Raleigh's distribution.

This is a good approach since it is very straight forward. However, in my opinion, it seems that the source code does not closely obey Jake's mathematical model. For the in-phase component, the author only consider one single ray at one time but did not sums up all the multipath rays at that specific time (the same for the quadrature phase component for that specific time). As the result, for any specific sampling time t(i), the complex envelope T(i) only make up of one single ray, e.g. T(1) is actually from the first ray(out of 5000 rays received) at
t(1), T(2) is actually from the second ray(out of 5000 rays received) at t(2) and so on... until the T(5000) which is actually the 5000-th ray at t(5000). I sincerely hope that the author can reconsider my point and correct me if I am wrong.
