If the channel is a gaussian and fading channel then B.sub.k =u.sub.k L.sub.k /[(E.sub.s /N. sub.0) log.sub. 10 e] where E.sub.s /N.sub.0 is the channel signal-to- noise ratio and log. sub.10 e is approximately equal to 0.434.Joachim Hagenauer...
a video controller board connected to said central processing unit whereby said video controller board processes video and audio data into a composite format for eventual video display and provides necessary decoding, a video board that takes said composite format and outputs a video signal for displa...
The invention relates to a method and a decoder for source-controlled channel decoding using intra-frame correlation in the GSM system. The inventive channel decoder system for coded data in a frame format has a canal decoder (1) which optionally takes into account a priori information in ...
However, the resulting compressed bit stream becomes highly sensitive to channel noise. There have been several approaches to add error resiliency to an image coder. In this work we concentrate on the use of joint source-channel (JSC) methods. In particular, source-controlled channel decoding, ...
A method of source controlled channel decoding a bit of a received frame comprises: determining inter-frame a priori information based on correlation between corresponding elements Uk-l,n and Uk,n of successive frames; determining intra-frame a priori information based on correlation between ...
