“…The first way is to overcome the jitter by designing the waveform of pulse [ 29 , 30 , 31 ], which was a focus of attention a decade ago. The second way is to improve the accuracy of timing synchronization [ 32 , 33 , 34 ], which has been a concern in recent years. The third way is about weighted receivers [ 26 , 27 , 28 ], which can achieve good performance by overcoming the change in the shape of the pulse.…”

Time-hopping pulse position modulation (TH-PPM) stands out as a secure communication due to the pseudo-random characteristics of its time-hopping sequence. However, the conventional TH-PPM transceiver encounters challenges in implementation, particularly in achieving the requisite high precision for synchronization. This paper introduces a novel non-coherent Q-ary TH-PPM transceiver, designed to surpass the Bit error rate (BER) performance of conventional TH-PPM transceivers in scenarios under non-ideal synchronization conditions, which also being straightforward to implement. Firstly, we provide an overview of the conventional TH-PPM transceiver. Secondly, the novel TH-PPM transceiver is introduced. In this context, a novel method for generating the TH-PPM signal is proposed for the transmitter, and a parallel matched-filter algorithm, adapted to the new TH-PPM signal, is presented for the receiver. Subsequently, the investigation delves into an in-depth analysis of BER performance, considering both ideal synchronization conditions and non-ideal synchronization conditions, for both the conventional and the new TH-PPM transceiver. Furthermore, the paper proposes a numerical simulation to validate the theoretical findings. The results demonstrate that the new TH-PPM transceiver outperforms the conventional counterpart by showing better BER performance in scenarios with non-ideal synchronization conditions.

Digital envelope detection, self-correlation and high frequency sampling techniques are proposed for high data rate demodulation of on-off keying signals that are widely used in impulse radio ultra-wideband receivers. The proposed designs eliminate the requirement of complex synchronisation circuit architectures and algorithms. The presented circuits are all digital and can be utilised in the baseband synchronisation. The digital envelope detection and self-correlation methods are implemented in 130 nm complementary metal oxide semiconductor (CMOS) technology and concepts are verified with measurement results. Post-layout simulation results are given for the high frequency sampling technique. Measurements show that the digital envelope detector demonstrates successful operation up to 600 Mbps data rate with 2.1 mW power consumption. The self-correlator consumes 10 mW with 100 Mbps data rate in the measurements. The post-layout simulations results show that the high frequency sampler can operate at 2 mW with 500 Mbps data rate.
