Designing a non-ideal delay line (DL) with phase distortion in a transmitted-reference ultra-wideband system (TR-UWB) with an autocorrelation receiver (AcR) is a great technical challenge. Differing from the currently empirical design method of DL, in this paper a semi-analytic approach is proposed through Gaussian approximation of the expression for(More)
This paper analyses the bit error rate (BER) and capacity behaviour of orthogonal frequency division multiplexing (OFDM) and cyclic prefix based single carrier (CP-SC) systems using amplify and forward relay (AF) with two hops wireless channel type 1 (Rayleigh-AF-UWB) and channel type 2 (Exponentially decaying multipath-AF-UWB). We consider Saleh-Venezuela(More)
