Performance Analysis of Signal Detection using Quantized Received Signals of Linear Vector Channel
Kazutaka Nakamura
Performance analysis of optimal signal detection using quantized received signals of a linear vector channel, which is an extension of code-division multiple-access (CDMA) or multi…
Microscopic Analysis for Decoupling Principle of Linear Vector Channel
Kazutaka Nakamura, Toshiyuki Tanaka
This paper studies the decoupling principle of a linear vector channel, which is an extension of CDMA and MIMO channels. We show that the scalar-channel characterization obtained v…
Statistical Mechanics of Broadcast Channels Using Low Density Parity Check Codes
Kazutaka Nakamura, Robert Morelos-Zaragoza, David Saad +1
We investigate the use of Gallager's low-density parity-check (LDPC) codes in a broadcast channel, one of the fundamental models in network information theory. Combining linear cod…
Tighter Decoding Reliability Bound for Gallager's Error-Correcting Code
Yoshiyuki Kabashima, Naoya Sazuka, Kazutaka Nakamura +1
Statistical physics is employed to evaluate the performance of error-correcting codes in the case of finite message length for an ensemble of Gallager's error correcting codes. We…
