Error Coins

The comb pilot aided channel estimation in ofdm modulation is considered. The power of pilot subchannels is under the control.The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

This m-file finds the bit error rate performance of BPSK DS-SS system over (i) AWGN channel and (ii) Slow Rayleigh fading channel corrupted by AWGN. Compare the performance with simple BPSK system.In this simulation I have used two functions.So to see the result open all the files and then run...

it encodes and decodes binary msg using hamming codes and detect errors, correct single error.

Fixes x data so that interp1 doesn't return error:'The values of X should be distinct.'Checks for duplicate values in input 1D data array and returns array where all values are distinct. If duplicates are found, values are separate by small value (eps). useage:x = nonduplicate(x); yi =...

I was trying out modifications of the LMS algorithm so that it will converge faster and the mean square error will also be smaller. Getting to one of the drawbacks of LMS, that it has only one controllable parameter "mu", the selection of whose value will be the most critical from design point of...
