Re: Time-varying channel
as I know, the time-varying channel can be approximated as fourier basis expansion model, is there any useful materials for it?
I am sorry, but I am a beginner in turbo code. What I mean is how to get low-rate turbo code like 1/4 code rate in a common way.
Only add 1 more interleaver and convolutional encoder, Is it right?
Thank you very much!
The code rate (=1/4) can be obtained from mother code (=1/3) by repetiton.
Is there anybody who knows how to implemente the process ?
Thank you in advance!

Re: turbo code
Thank you for your kind reply, I am still wondering what is the punturing pattern of code rate (= 1/4) ?
The last question is arrangement of the output sequence, take the code rate (=1/2) for example, the output should be I1 A1 I2 B2 I3 A3 I4 B4, is it right?
Re: turbo code
I am not familiar with turbo code, are there any files that demonstrate the concrete procedure of implementing different code rate?
thank you!
hi I need help on turbo code.
Is there anybody who have simulated such a system in which the code rate can be adjusted, namely 1/2, 1/3, 3/4 and so on?
thank you for your help!
hsdpa simulation
hi
I am a beginner in matlab and I want to simulate a link-level hsdpa system, can anybody give me an example or matlab code, thank you!
