“…where P k is the transmission power of the k-th user, and ICI k is the total interference of user k. In addition, there is a relationship of P s = 1 − (1 − P B ) b between the BER P B and the symbol error rate P s provided that b is even number [11]. In addition, assuming one packet contains N s symbols, so the number of error symbols is N e = N s P s .…”

In order to realize the notion of 'anytime, anywhere' communication for high-speed train passengers, the Long Term Evolution for Railway is designed to provide broadband accesses and reliable communications for high-speed train passengers. However, with the increase of train speed, the system is subject to high bit error rate, Doppler frequency shift, and call drops. This paper is trying to solve these problems by employing the Multiple-Input Multiple-Output technique and access control schemes. The goal is to provide higher quality of services such as data rate, reliability, and delay for train passengers. Physical layer performance analysis and access control schemes are proposed in a two-hop model. Handovers and service types are also considered. Simulation results show that proposed models and schemes perform better in improving the quality of services.

Abstract-Recently, physical-layer network coding (PNC) attracts much attention due to its ability to improve throughput in relay-aided communications. However, the implementation of PNC is still a work in progress, and synchronization is a significant and difficult issue. This paper investigates the feasibility of synchronous PNC with M -ary quadrature amplitude modulation (M -QAM). We first propose a synchronization scheme for PNC. Then, we analyze the synchronization errors and overhead of potential synchronization techniques, which includes phase-locked loop (PLL) and maximum likelihood estimation (MLE) based synchronization schemes. Their effects on the average symbol error rate and the goodput are subsequently discussed. Based on the analysis, we perform numerical evaluations and reveal that synchronous PNC can outperform conventional network coding (CNC) even when taking synchronization errors and overhead into account. The theoretical throughput gain of PNC over CNC can be approached when using the MLE based synchronization method with optimized training sequence length. The results in this paper provide some insights and benchmarks for the implementation of synchronous PNC.

In this paper we study the effect of the FBMC intrinsic interference on the error rate performance in the presence of a phase error. We focus our study on the symbol error rate (SER) performance in additive white Gaussian noise (AWGN) channel, and we derive the SER performance expressions for any 2 m -PAM (pulse amplitude modulation) data mapping and a phase error φ. The SER performance also depends on the probability distribution of the interference term. Since the intrinsic interference is generated from the transmitted data symbols, the probability distribution of the interference is related to the data symbol mapping. We suggest to approximate the interference probability distribution to Gaussian one for the high order constellations, and simplify the analytical expression of the SER performance. The analytical expressions developed in the paper are checked and confirmed by numerical simulations. We will show in the paper that the performance curves obtained by simulation and theoretical analysis are the same for high order constellation where the approximation of the interference to the Gaussian one is suitable.
