Closed-loop space-time block codes (STBCs) for multiple transmit antennas, using phase feedback, have recently been proposed. These codes, with perfect phase feedback, achieve full diversity. However, a large number of feedback bits are required, which is not practical. In this paper, we analyze a quantized two-phase feedback scheme for eight transmit antennas and one receive antenna system with full...
Wireless Body Area Networks (WBANs) have been recently proposed due to increasing technical demands on wearable computing and healthcare systems. Advanced studies for any communication system begin with a channel model. This paper examines channel models for signal propagation around the surface of the body at 915 MHz and 2.45 GHz (ISM bands). The applications of multiple-input-multiple-output (MIMO)...
