About Course

MicrophoneCourse is focused on error correcting coding techniques. Power and energy spectral density, autocorrelation, waveform coding, DPCM, orthogonalization, PAM, ASK, FSK, PSK and derivatives, correlation type and matched filter type detectors, ML and MAP criterion, channel coding and channel capacity, block codes, Hamming codes, error detection and error correcting codes, cyclic codes, convolutionary codes, trellis diagrams and Viterbi’s algorithm subjects are evaluated. Here is the course description document. Lab description document is here.
