Interleaving is simply a technique used in data communication to protect or avoid large error to bursty data. The key point of interleaving is to disperse some bits( suppose there are “b” bits) of the code into some ( suppose to be “n” bursts) burst sequences so as to change the adjacent relationship between bits. Why Interleaving? Burst error are the errors that occur in a sequence or as groups. The Benefits of Interleaving Practice. V    This process is known as interleaving. After frequency interleaving, the local deep fading is averaged over the whole bandwidth of the system. These framing pulses mark the boundary between the packets.
