In this paper, new results for the multivariate Rayleigh distribution with an arbitrary correlation matrix are presented. By using an efficient tridiagonalization method based on House-holder matrices, closed-form union upper bounds for its joint probability density and cumulative density functions are derived. Based on the proposed mathematical analysis, a(More)
This paper will review the evolution of wearable textile antennas over the last couple of decades. Particular emphasis will be given to the process of embroidery. This technique is advantageous for the following reasons: (i) bespoke or mass produced designs can be manufactured using digitized embroidery machines; (ii) glue is not required and (iii) the(More)
Several cooperative transmission techniques have been studied in previous research works but very few of them have considered the trade-off between diversity gain and energy efficiency, which is important in cases, such as wireless sensor networks. Two cooperative transmission techniques are examined, namely decode-and-forward (DF) and network coding (NC),(More)
