MATLAB: What is a Nakagami channel

nakagami channel; noise; nakagami-m; signal processing; powerline communication

Hi everyone, as i am not an expert in telecom, i need some clarifications please. 1: is there a difference between considering a Nakagami channel with X noise (example AWGN) and a channel with a Nakagami Noise? 2: is there a closed form for a Nakagami -m Noise that can be used in some variables calculation,like system capacity? Thank you in Advance

Nakagami-m fading channel is a more generalised fading channel representation. Channels and noise are two different matters. Noise always exists in a communication system. However, fading channel distribution can be considered based on the position of the nodes and the existence of line-of-sight component in the propagation signal. I suggest you read this:

Hi, If you have the Statistics Toolbox, you can use histfit() with the 'nakagami' option.

You can also use mle() with the 'nakagami' option to get the maximum likelihood estimates of the parameters of the Nakagami distribution.

Hi,

This error occours when the data vector you give, contains negetive values. Remove the negetive values and the error will be no more. For example

a = randn([1,10]); % It may give you negetive values
so histfit(a,10,'nakagami');
will give u error.
However a =randi(20,[1,30]); % It will give you only positive values
so histfit(a,10,'nakagami'); will not give u any error

Hope this helps.

Happy to help
