Reservoir Computing (RC) is a recent neurologically inspired concept for processing time dependent data that lends itself particularly well to hardware implementation by using the device physics to conduct information processing. In this paper, we apply RC to channel estimation in Orthogonal Frequency Division Multiplexing (OFDM) systems. Due to the multipath propagation environment between a transmitter...
In most existing channel decision mechanisms for cognitive radio (CR), it is assumed that instantaneous channel state information (CSI) and primary user (PU) activity information is available. However, in many CR network applications, frequent channel sensing and estimation could introduce excessive overhead and reduce system throughput. Channel sensing by secondary users (SUs) may also not be completely...
As block coding and intelligent receiver combining in multi-antenna systems moves from the theorectical into the physical domain, it is necessary to apply robust analysis to the problems encountered with the development of real radio systems that are often overlooked during theoretical development of methods and processes. One such problem is the lack of synchronization between the transmitter and...
