“…In [10], Zhang et al investigated the usage of lowresolution ADCs in communication systems from various angles such as detection, channel estimation and precoding. An ML detector for quantized distributed reception was presented in [11], where the complexity of the detector grows exponentially with high signal constellations, number of transmit antennas and number of users in the uplink.…”

This paper considers a low-resolution wireless communication system in which transmitted signals are corrupted by fading and additive noise. First, a universal lower bound on the average symbol error probability (SEP), correct for all M -ary modulation schemes, is obtained when the number of quantization bits is not enough to resolve M signal points. Second, in the special case of M -ary phase shift keying (M -PSK), the optimum maximum likelihood detector for equiprobable signal points is derived. Third, utilizing the structure of the derived optimum receiver, a general average SEP expression for the M -PSK modulation with n-bit quantization is obtained when the wireless channel is subject to fading with a circularlysymmetric distribution. Finally, an extensive simulation study of the derived analytical results is presented for general Nakagamim fading channels. It is observed that a transceiver architecture with n-bit quantization is asymptotically optimum in terms of communication reliability if n ≥ log 2 M + 1. That is, the decay exponent for the average SEP is the same and equal to m with infinite-bit and n-bit quantizers for n ≥ log 2 M + 1. On the other hand, it is only equal to 1 2 and 0 for n = log 2 M and n < log 2 M , respectively. Hence, for fading environments with a large value of m, using an extra quantization bit improves communication reliability significantly.Index Terms-Maximum likelihood detection, low-resolution ADC, symbol error probability.

“…Therefore, it is undoubted that the use of high‐resolution ADCs results in a surge of power consumption as the number of antennas goes large, which may limit the implementation of the massive MIMO. To overcome this challenge, the use of low‐resolution ADCs in the upcoming massive MIMO systems is a potential solution …”

In this paper, we analyze the performance of uplink massive multiple‐input–multiple‐output (MIMO) systems with variable‐resolution analog‐to‐digital converters (ADCs), ie, each receive antenna uses a pair of ADCs with arbitrary resolution. Given that the minimum mean square error (MMSE) or the maximum ratio combining (MRC) detection can be employed at the base station (BS); using perfect channel state information (CSI) and results from the random matrix theory, we first derive the closed‐form approximate expression of sum achievable rate for these two type detectors, respectively. Suppose that only imperfect CSI is available at the BS. We then provide a scheme to estimate the equivalent channel based on the classical linear MMSE technique and derive the sum achievable rate using the estimated equivalent channel. Moreover, to improve the system performance, we take the impacts of channel estimation error and quantization noise into account and achieve the corresponding analytical results. Finally, simulation results are presented to validate our theoretical analysis and provide some insights on the massive MIMO systems with variable resolution ADCs. Additionally, for the MMSE and MRC detector with perfect and imperfect CSI in the considered architecture, the trade‐off between the spectral efficiency and the energy efficiency is investigated as well.

“…For the challenge of the explosive mobile traffic growth, the mmWave is a promising candidate in all respects. In the mmWave networks, directional antenna and beamforming technique are common means of compensating for the non-negligible path loss [1][2][3][4]. Besides, concurrent transmission can significantly increase the system throughput [5].…”

The small cells in millimeter wave (mmWave) have been utilized extensively for the fifth generation (5G) mobile networks. And full-duplex (FD) communications become possible with the development of self-interference (SI) cancellation technology. In this paper, we focus on the optimal allocation of the sub-channels in the small cells deployed densely underlying the mmWave networks. In order to improve the resource utilization and network capacity, device-to-device (D2D) communications are adopted in networks. For maximizing the system throughput, we propose a cooperative sub-channel allocation approach based on coalition formation game, and theoretically prove the convergence of the proposed allocation algorithm. The utility of the coalition formation game is closely related to the sum system throughput in this paper, and each link makes an individual decision to leave or join any coalition based on the principle of maximizing the utility. Besides, a threshold of the minimum transmission rate is given to improve the system fairness. Through extensive simulations, we demonstrate that our proposed scheme has a near-optimal performance on sum throughput. In addition, we verify the low complexity of the proposed scheme by simulating the number of switch operations.
