Wimax Baseband Algorithms

Started by walter2k February 23, 2008
Hi,


How complicated are Wimax baseband algorithms as compared to voice
algorithms (eg G.711). 

I am new to wimax and need to have an estimate of the time required to
code and optimize wimax baseband algorithms.

It's apples and oranges. If you are doing a basis of estimate, base it on something similar like 802.11. John

hopefully this thesis should help you to further dig in and it gives all algorithms on wimax master_018_2005.pdf http://db.s2.chalmers.se/download/masters/master_018_2005.pdf

I don't even know where to begin comparing the two! You give very little background on your experience, so let me assume that you are familiar with speech coding systems but not with communication receivers. The hardest part will probably be the synchronization part of Wimax, especially if you have never dealt with OFDM receivers before. This is usually the most "shocking" part for those coming from a speech or source coding background. The difficulty is of course scaled according to how much synchronization you need to do, determined by the architecture (all-digital? part analog? sampling clock offset? direct conversion?) and the component ratings (clock drift, jitter, etc.). Notice that the link posted by Particlereddy doesn't even consider synchronization. Julius
