FFT block codes have been proposed as an error correction code similar to RS codes. In this Letter this novel technique is applied to speech signals with erasures. A convolutional method is also implemented which is capable of reconstructing oversampled speech signals with a certain percentage of lost samples, given that the average sampling rate remains higher than the Nyquist rate. The convolutional method uses FIR digital filters in the time domain as opposed to low pass filtering the FFT… CONTINUE READING
