Abstract :
We consider the problem of transmission of independent and correlated Gaussian sources over the two user Gaussian Broadcast Channel (GBC). We present a low complexity, low delay, analog joint source channel coding communication system based on extensions of existing Nested Quantization techniques. Simulations results show that the resulting performance is close to the optimal theoretical limits for several cases of interest.
