Accelerating Iterative Detection for Spatially Coupled Systems by Collaborative Training
Keigo Takeuchi
This letter proposes a novel method for accelerating iterative detection for spatially coupled (SC) systems. An SC system is constructed by one-dimensional coupling of many subsyst…

Performance Improvement of Iterative Multiuser Detection for Large Sparsely-Spread CDMA Systems by Spatial Coupling
Keigo Takeuchi, Toshiyuki Tanaka, Tsutomu Kawabata
Kudekar et al. proved that the belief-propagation (BP) performance for low-density parity check (LDPC) codes can be boosted up to the maximum-a-posteriori (MAP) performance by spat…

A Greedy Algorithm of Data-Dependent User Selection for Fast Fading Gaussian Vector Broadcast Channels
Keigo Takeuchi, Tsutomu Kawabata
User selection (US) with Zero-forcing beamforming is considered in fast fading Gaussian vector broadcast channels with perfect channel state information (CSI) at the transmitter. A…
