Closed-loop MIMO system can provide dramatic gains in channel capacity. However, mobile terminal (MT) must feedback the downlink channel state information (CSI) to Base station (BS), and transmitting CSI is a heavy burden consuming considerable uplink bandwidth. To address this bottleneck problem, a zero-overhead downlink CSI feedback scheme is proposed in this paper. After receiving the downlink...
Adaptive modulation and coding (AMC) scheme suffers performance degradation with the signaling feedback delay, as channel state information (CSI) is outdated with time variant channel. In this paper, we propose a robust AMC scheme to mitigate the effect of signaling feedback delay, especially in vehicular environments. Channel information estimated in current time interval is utilized to obtain the...
In this paper, we investigate a novel MIMO transceiver with space-time-hopping code combing pulse position modulation (STH-PPM) for UWB time division multiple access (TDMA) system. Moreover, we propose a new approach called second-order statistics (SOS) with unknown channel state information (CSI) for receiver detection. This new transceiver does not require any training or pilot symbols or decision...
