In this paper, We first propose a design rule for constructing a proper multilayer code for MultipleInput-Multiple-Output(MIMO) networks A number of recent source coding techniques compress the source signal into multiple layers such that a destination is able to reconstruct the original signal (with some distortion) even if it has not received all the layers. | ISSN:2249-5789 M Thejovathi et al, International Journal of Computer Science & Communication Networks,Vol 3(2), 84-96 Multilayer Coding Mechanisms for Broadcasting over MIMO Networks 1 2 M.

The recent development of multimedia able to reconstruct the original signal (with some services motivates researchers to develop new distortion) even if it has not received all the layers. source and channel coding techniques to support Implementation of such source coding techniques in transmission of higher data rates. In some wireless networks requires the application of coding applications such as video broadcasting, the mechanisms (such as multilayer coding) which allow Channel State Information (CSI) is not available at the unequal error protection for different layers of the transmitter side and therefore the message can be transmitted data. And also, we study the performance decode totally or partially at the receiver if the of multilayer coding for quasi-static fading channels quality of channel is above some certain threshold. where the source and the destination are equipped One common transmission approach is to encode and with multiple antennas and the Channel-State- transmit the message using one layer codes. With this Information (CSI) is only known at the destination. We method, the receiver can decode either the total limit the study to the scenarios where the .
