“…To obtain the semi-analytical BER curves, we modeled a baseband TRPC system, in which a training sequence with length N t symbols is used to estimate the channel-dependent parameters required in (22) and (23) for each channel realization. This training sequence consists of N t /2 consecutive symbols "+1" and N t /2 consecutive symbols "−1".…”

Transmitted reference pulse cluster (TRPC) signaling was recently proposed and developed for noncoherent ultra-wideband (UWB) communications. In this paper, a practical passband TRPC-UWB system is designed and analyzed to deal with the carrier frequency offset, phase offset and phase noise inherent in voltage-controlled oscillators (VCO) of the transmitter and the receiver. Based on a general model of noisy VCO and employing some reasonable assumptions, an equivalent linear time-invariant (LTI) analytical model is obtained to facilitate the bit error rate (BER) analysis. Our analysis shows that the constant carrier frequency offset and the phase offset can be removed by employing the passband transmitter and the noncoherent receiver. Furthermore, a semi-analytical BER expression is derived to show the impact of phase noise on the system error performance. Simulation results validate the semi-analytical expressions and both of them indicate that TRPC is more robust to the effect of phase noise than conventional transmitted reference (TR) and coherent UWB Rake receivers.INDEX TERMS Bit error rate (BER) performance, phase noise, transmitted reference pulse cluster (TRPC), impulse radio, ultra-wideband (UWB).Recently, the TRPC-UWB system was further developed and improved from various practical aspects [16]- [28].

“…Meanwhile, integration length, decision threshold and the synchronization point must be optimized, which increase the complexity of this method. Transmitted-Reference receiver technology [2] uses the correlation between the reference signal and the receiving signal, which simplifies the system complexity and reduces the synchronization precision. But the system BER and the system emission energy of this method is poor.…”

An average Transmitted-Reference (TR) receiver scheme based on orthogonal codes is proposed for improving the bit error rate (BER) performance and the transmitting rate of Ultra-wideband (UWB) TR receiver systems in coal mine. Orthogonal codes are used for modulating the reference pulses and the data pulses in each frame of every bit. Since the orthogonality of the two codes, the inter-pulse interference (IPI) is greatly reduced. Then the decoding reference pulses and the data pulses are averaged in a frame, which decreases the noise in the reference pulses and the data pulses. Finally, I demonstrate this optimal receiver scheme by the simulation in the coal mine roadway ultra-wideband channel model. Detailed simulation experiments are presented to validate the effectiveness of this proposed method. The experimental results show that this method can not only efficiently reduce the noise interference in receiving signals, but also can provide higher transmission rate, which make UWB signal receiving in coal mines more accurately.
