Description: 本文考虑了一种新的系统模型，它结合了通用收发器硬件损伤在BSs（配备大型天线阵列）和单天线用户设备（UE）。与传统硬件的传统情况相反，我们表明硬件损伤在信道估计精度和每个UE的下行链路/上行链路容量上创建有限天花板。令人惊讶的是，容量主要受限于UE的硬件，而大规模阵列中的损伤的影响逐渐消失，并且用户间干扰（特别是导频污染）变得可以忽略不计。此外，我们证明了大量的MIMO所提供的巨大自由度可以用来减少发射功率和/或容忍较大的硬件损伤，这允许使用廉价和节能的天线元件。(This paper considers a new system model that incorporates general transceiver hardware impairments at both the BSs (equipped with large antenna arrays) and the single-antenna user equipments (UEs). As opposed to the conventional case of ideal hardware, we show that hardware impairments create finite ceilings on the channel estimation accuracy and on the downlink/uplink capacity of each UE. Surprisingly, the capacity is mainly limited by the hardware at the UE, while the impact of impairments in the large-scale arrays vanishes asymptotically and inter-user interference (in particular, pilot contamination) becomes negligible. Furthermore, we prove that the huge degrees of freedom offered by massive MIMO can be used to reduce the transmit power and/or to tolerate larger hardware impairments, which allows for the use of inexpensive and energy-efficient antenna elements.)

Description: 盲源分离(BSS: Blind Source Separation)，又称为盲信号分离，是指在信号的理论模型和源信号无法精确获知的情况下，如何从混迭信号(观测信号)中分离出各源信号的过程。盲源分离和盲辨识是盲信号处理的两大类型。盲源分离的目的是求得源信号的最佳估计，盲辨识的目的是求得传输通道的混合矩阵。(Blind source separation (BSS: Blind Source Separation), also known as blind signal separation, refers to how to separate each source signal from the aliased signal (observed signal) when the theoretical model of the signal and the source signal cannot be accurately known)

Description: One of the major challenges which prevents the coordinated multipoint (CoMP) communications concept from being widely deployed in new cellular systems is timing synchronization. In order to achieve the gains promised by CoMP systems, the user equipments’ (UEs) signals in uplink (UL) or the base stations’ (BSs) signals in downlink (DL) should be synchronized such that the time difference of arrivals (TDOAs) do not exceed the cyclic prefix (CP) length of the transmitted signals; Otherwise the system suffers from unavoidable integer time offsets. These offsets lead to asynchronous interference in terms of inter-carrier, inter-block and inter-symbol interference (ISI). This limits the percentage of area within a cell which can be covered by cooperation and imposes an upper bound on this area. In this paper, we investigate this problem in the UL and by using geometrical and semi-analytical approaches, we define this upper bound. Also, by characterizing an accurate mathematical model for the asynchronous interference in Rayleigh fading channels, we were be able to employ a standard MMSE-based receiver that mitigates this interference. Furthermore, a typical joint channel and delay estimation block is incorporated into the receiver to examine its performance with estimation errors.
