This paper presents the performance of impulse radio ultra wide band up-converted in the 60 GHz band for high rate ad hoc network. We evaluate the performance of a multiuser transmission system based on time hopping code division multiple access. The analytical bit error probability depending on the number of objects in the room is derived. We use a non parametric estimation of the received power...
In this paper, we propose a novel autocorrelation receiver (AcR) for transmitted-reference signaling that alleviates excessive noise collection. Specifically, we employ a stop-and-go strategy based on energy detection in the AcR to selectively collect portions of effective signal. This avoids noise collection from time regions within the integration interval that do not contain useful energy contributions...
In this paper, we mathematically analyze the performance of a near-interference erasure scheme for TH-PPM UWB systems and derive an equation for an optimum threshold which minimizes the bit error rate (BER). We also apply the optimum threshold derived mathematically to practical TH-PPM UWB systems and investigate the effect of the threshold on the system performance. Finally, we compare the BER performance...
In this paper, we implement a MMSE RAKE receiver in a very fast system simulator for time-hopping ultra-wideband (TH-UWB) system. Since the transmitted waveform is masked by transmitted-distorted-received waveform (TDR), a typical multiuser structure does not exist and the implementation of any multiuser detector in this algorithm might be a difficult issue. Therefore, applying this method, in this...
