Abstract—Cooperative diversity techniques can improve the transmission rate(More)
—Cooperative diversity is a useful technique to increase reliability and throughput of wireless networks. To analyze the performance gain from cooperative diversity, outage capacity is an important figure of merit that captures the inherent diversity-multiplexing trade-off in cooperative diversity schemes. In this paper we derive the outage capacity for(More)
In this paper, a study of optimised bucket widths in calendar queue for discrete event simulator is presented. It is shown that the performance of calendar queue can vary noticeably depending on the chosen width factor (W f). Existing algorithms appears to perform reasonably well in general situations. However , under certain scenarios these algorithms may(More)
In this paper, the rate-2 pcu STF coding schemes that can be efficiently implemented for use in multiband UWB-MIMO systems has been presented. These proposed STF codes are constructed based on the multi-dimensional constellation preceding so that the rotated version of the information symbols are spread across adjacent subcarriers and sent over(More)
