“…More importantly, analytical results show that the coverage probabilities of both types of networks increase as a non-decreasing concave function with the antenna array size. It will be interesting to extend the proposed analytical framework to more advanced precoding techniques, e.g., hybrid precoding [29], [30]. Moreover, a coverage analysis that includes the beam misalignment caused by the imperfect channel information also is a promising future research direction.…”

“…With Theorem 1 at hand, in order to obtain the specific coverage probability expression for a certain kind of channel gain g, the only parameters required to be determined are the entries {c k } M −1 k=0 in the matrix C M . While we focus on analog beamforming, the framework proposed in this section is also applicable for mmwave networks adopting other transmission techniques, e.g., hybrid precoding [29], [30]. In the following two sections, we shall derive the coverage probabilities for different network settings and antenna patterns.…”

Abstract-Millimeter wave (mm-wave) communications is considered a promising technology for 5G networks. Exploiting beamforming gains with large-scale antenna arrays to combat the increased path loss at mm-wave bands is one of its defining features. However, previous works on mm-wave network analysis usually adopted oversimplified antenna patterns for tractability, which can lead to significant deviation from the performance with actual antenna patterns. In this paper, using tools from stochastic geometry, we carry out a comprehensive investigation on the impact of directional antenna arrays in mm-wave networks. We first present a general and tractable framework for coverage analysis with arbitrary distributions for interference power and arbitrary antenna patterns. It is then applied to mm-wave ad hoc and cellular networks, where two sophisticated antenna patterns with desirable accuracy and analytical tractability are proposed to approximate the actual antenna pattern. Compared with previous works, the proposed approximate antenna patterns help to obtain more insights on the role of directional antenna arrays in mm-wave networks. In particular, it is shown that the coverage probabilities of both types of networks increase as a non-decreasing concave function with the antenna array size. The analytical results are verified to be effective and reliable through simulations, and numerical results also show that largescale antenna arrays are required for satisfactory coverage in mm-wave networks.

“…Moreover, the performance of the codebook based technique is severely inferior to the one of the codebook based solution, especially for high SNR values. This is due to the codebook use that restricts the solution set of the analog counterpart, as it was also observed in [4], [5].…”

Abstract-Recent advances in Milimeter wave (mmWave) band mobile communications may provide solutions to the increasing traffic demand in modern wireless systems. Even though mmWave bands are scarcely occupied, the design of a prospect transceiver should guarantee the efficient coexistence with the incumbent services in these bands. To that end, in this paper, two underlay cognitive transceiver designs are proposed based on a hybrid Analog/Digital transceiver architecture that enables the mmWave spectrum access while controlling the interference to the incumbent users with low hardware complexity and power consumption. The first cognitive solution designs a codebook free cognitive hybrid pre-coder by maximizing the mutual information between its two ends subject to interference, power and hardware constraints related to the analog counterpart. The second solution is codebook based and exhibits less complexity than the first one at the cost of inferior spectral efficiency. A novel codebook free solution for the post-coder at the cognitive receiver part is further proposed, based on a hardware constrained Minimum Mean Square Error criterion. Simulations study the performance of both the proposed hybrid approaches and compare it to the one of a fully digital solution for typical wireless environments.

“…A simple solution is to select L ′ = 2K out of the L RF chains, which reduces to the trivial case. Otherwise, we could design the remaining L − 2K columns of F r resorting to random phases as in [31], or through sophisticated optimization methods like in [32], which in general are less likely to yield tractable expressions for performance analysis. Hence, in this paper, we focus on the case 2K = L and will show its asymptotic optimality under the considered scenario.…”

Abstract-We consider a multi-pair massive multiple-input multiple-output (MIMO) relay network, where the relay is equipped with a large number, N , of antennas, but driven by a far smaller number, L, of radio frequency (RF) chains. We assume that K pairs of users are scheduled for simultaneous transmission, where K satisfies 2K = L. A hybrid signal processing scheme is presented for both uplink and downlink transmissions of the network. Analytical expressions of both spectral and energy efficiency are derived with respect to the RF chain number under imperfect channel estimation. It is revealed that, under the condition N > 4L2 /π , the transmit power of each user and the relay can be respectively scaled down by 1/ √ N and 2K/ √ N if pilot power scales with signal power, or they can be respectively scaled down by 1/N and 2K/N if the pilot power is kept fixed, while maintaining an asymptotically unchanged spectral efficiency (SE). While regarding energy efficiency (EE) of the network, the optimal EE is shown to be achieved when Pr = 2KPs, where Pr and Ps respectively refer to the transmit power of the relay and each source terminal. We show that the network EE is a quasi-concave function with respect to the number of RF-chains which, therefore, admits a unique globally optimal choice of the RF-chain number. Numerical simulations are conducted to verify our observations. Index Terms-Massive MIMO relay, hybrid processing, spectral efficiency (SE), energy efficiency (EE), limited RF chain.
