IT++ Polar Code

Rob — Thu, 05 Aug 2010 17:51:15 +0000

I’ve written some IT++ programs to train and simulate polar codes. Check it out over here.

Matlab UMTS Turbo Code

Rob — Tue, 08 Jun 2010 17:24:18 +0000

This Matlab code plots the BER, EXIT chart and iterative decoding trajectories of the UMTS turbo code.

Matlab code for generating Huffman codebooks

Rob — Wed, 24 Feb 2010 12:07:24 +0000

I’ve added some Matlab code that I wrote to generate a Huffman codebook for a specified set of symbol probabilities. You can get it from here.

Matlab code for repeat accumulate codes

Rob — Wed, 26 Aug 2009 19:38:38 +0000

I’ve uploaded some Matlab code for drawing EXIT chart, iterative decoding trajectories and BER plots for half-rate repeat accumulate codes. You can download it here.

C fixed-point BCJR

Rob — Wed, 17 Jun 2009 15:48:10 +0000

I’ve added some C code for the BCJR used in fixed-point UMTS turbo codes.

I’ve put a bunch of my teaching resources on the website.

C++ classes for simulating block-based precoders

Rob — Mon, 01 Sep 2008 13:32:59 +0000

Hi. I’ve uploaded some C++ classes for simulating block-based precoders. Take a look at the page in the resources section of this site.

Source code for calculating the DCMC capacity in Matlab

Rob — Fri, 08 Aug 2008 11:02:38 +0000

I’ve uploaded some Matlab source code I wrote that lets you calculate the Discrete-input Continuous-output Memoryless Channel (DCMC) capacity of AWGN and uncorrelated Rayleigh fading channels for BPSK, QPSK, 8PSK and 16QAM. Check it out here…

Source code for drawing EXIT charts in Matlab

Rob — Fri, 01 Aug 2008 17:11:12 +0000

I’ve uploaded some source code I wrote that lets you draw EXtrinsic Information Transfer (EXIT) charts in Matlab. These help you characterise the iterative decoding convergence of turbo-like codes. Check it out here…

RobProb uploaded

Rob — Mon, 26 Nov 2007 12:26:11 +0000

I’ve uploaded the source code and documentation of my RobProb C++ data types. These are really handy for implementing Soft-In Soft-Out (SISO) decoders.
