“…The error betweenĥ and h also influences the communication quality. Second, it is only useful in PAM while practical UWB communication often adopts PPM [18]. Although we generate a template signal, we cannot compare it to original signal and confirm the polarity of code in PPM.…”

“…Employing the central limit theorem and approximating the distribution of the interference by the Gaussian distribution is a well-known technique in the literature that is usually used to obtain a better insight on the performance of communication systems [29][30][31]. In the following, we use the same approach to obtain a more tractable expression for the MUE outage probability.…”

With growing demand for high data rates, the mobile network has faced excessive traffic and it seems that one of the few long-term solutions to this problem is employing femtocells which improve capacity and indoors coverage. In the typical femtocell networks, co-and cross-layer interferences caused by simultaneous transmission of macrocell base stations and femtocell access points in the same frequency band, results in dead spots especially if femtocells are densely employed. In this study, to mitigate the interference and improve the system's performance, the authors study the application of time-hopping approach. Particularly, the impact of aggressive signals of femto access points on a macro user equipment located in the second tier, that is, the femtocell coverage area, is analysed and the semi-closedform expression for the system outage probability is derived. Based on the analysis, they also simulate the transmission capacity (TC) that represents the total capacity of the co-channel two-tier networks with outage constraints. Next, employing Gaussian approximations, they derive upper and lower bounds on the outage probability. These bounds provide better insight on the effect of system's parameters on its performance. Their numerical results show that the time-hopping technique significantly reduces the outage probability and therefore increases the TC of two-tier networks.

“…Since the information in IR-UWB systems is transmitted with short pulses (< 2 ns), signal energy has been spread over the frequency band of up to 10 GHz [1]. Many modulation schemes for the application in IR-UWB systems are proposed, like pulse amplitude modulation (PAM) [2], pulse position modulation (PPM) [3,4], pulse shape modulation (PSM) [5], on-off-keying (OOK) [6], binary phase-shift keying (BPSK) [7,8], pulse interval modulation (PIM) [9], etc.…”

Abstract:Research of impulse radio ultra-wideband (IR-UWB) systems has been extensively increasing in recent years due to their high power efficiency, high data rates and low hardware complexity. The choice of the modulation scheme used in an IR-UWB system has a great impact on its overall performances. In this paper, the biorthogonal pulse position modulation (BPPM) scheme for the application in transmitted reference (TR) IR-UWB communication systems is proposed. Performances of the BPPM scheme over two different IEEE 805.15.3a channel models in a multi-user environment are analysed and compared to the performances of the pulse position modulation (PPM) scheme. The results show that the BPPM scheme outperforms the PPM scheme in terms of bit error rate (BER), data rate and hardware complexity. Additionally, the influence of different system parameters on the BPPM performances in TR IR-UWB systems is analysed and possible trade-offs are proposed.
