Finished the paper for ISIT on Lossless Source Coding with Polar Codes.

Continuing research on decoding of RS codes, looking into FFT on finite fields.

Continued work on linear form decoding paper.

Setting up contact within the 4GBB consortium.

Started working on modulation and coding for DSL.

Submitted a chapter of phd thesis to IEEE Transactions on Communications.

Working on RS codes over prime fields, multiplication maps nicely to GP CPU.

RS codes on prime fields are fast. Algorithms for FFTs are neat when prime is chosen correctly.

Several interesting options for coding on DSL. Looking at coded modulation with shaping and what we can contribute to the 4GBB consortium.

Wrote a paper for the WIC in Rotterdam about the RS codecs.

Finished a paper about coded modulation for storage with N. Bouman (his MSc work back in Enschede.

Found an interesting technique for signaling on DSL lines. May have applications in other fields also.

Wrote a patent about the technique and made some initial verifications. Seems to work very well.

Paper for ISIT is accepted and has to be slightly adjusted

Preparing a patent for the signaling technique.

Follow-up research on the coding methods for DSL

Patent is filed and looking into other field and applications.

Extending the technique to have even a better performance.
