This paper considers TCQ and LDPC codes for the quadratic Gaussian Wyner-Ziu problem. After TCQ of the source input X, LDPC codes are used to implement Slepian-Wolf coding of the quantized source input Q(X) given the side information Y at the decoder. Assuming ideal Slepian-Wolf coding in the sense of achieving ,the theoretical limit H (Q (X) I Y) , it is(More)
Multiterminal (MT) source coding refers to separate lossy encoding and joint decoding of multiple correlated sources. This paper presents two practical MT coding schemes under the same general framework of Slepian-Wolf coded quantization (SWCQ) for both direct and indirect quadratic Gaussian MT source coding problems with two encoders. The first asymmetric(More)
This work considers the quadratic Gaussian multiterminal (MT) source coding problem and provides a new sufficient condition for the Berger-Tung sum-rate bound to be tight. The converse proof utilizes a set of virtual remote sources given which the MT sources are block independent with a maximum block size of two. The given MT source coding problem is then(More)
We perform asymmetric code design for remote multiterminal source coding (the CEO problem [1,2]) in the quadratic Gaussian case. 1 are i.i.d. random noises that are independent of each other and. For remote multiterminal source coding [1–3] of , to achieve the minimum sum rate of the two independent encoders subject to a fidelity criterion 3 , theoretical(More)
