The inter leaver or De-inter leaver delay is 2MN symbol times. M(N-1)+1 memory cells needs to be filled before transmission can begin. Thus the minimum end to end delay is 2MN-2M+2 symbol times, not including any channel propagation delay.

The cross interleave reed Solomon error control scheme in the CD system involves both correction and concealment of errors.

Compact disc digital audio system is used for both digital storage and reproduction of audio signals.

There is a trade off between error correction and erasure correction, the larger the error correcting capability used the smaller will be the erasure correcting capability.

The decoder step consists of both De-interleaving and decoding which are performed in the reverse order of encoding steps.

Separating the symbols in time effectively changes a channel with memory into a memory-less one.

A concatenated code is the one that uses two levels of coding, inner code and outer code to achieve desired error performance.

Some of the sources of channel errors are some unwanted particles, air bubbles, finger prints, scratches etc.

A channel that exhibits multi-path fading where the signal arrives at the receiver over two or more different paths. This channel has memory, exhibits mutually dependent signal transmission impairment.

The function of the interpolation function is to add new samples estimated from the reliable ones in place of unreliable ones.
