“…As explained in [30], the virtual channel model for a sparse channel provides a discretized approximation of the channel response that reduces the task of estimating H to that of detecting some non zero coefficientes in the virtual channel matrix. Neglecting this grid quantization error, we have (13) Hv E e GM s xGB s contains the path gains of the …”

Precodinglcombining and large antenna arra y s are essential in millimeter wave (mmWave) s y stems. In traditional MIMO s y stems, precodinglcombining is usuall y done digitall y at baseband with one radio frequenc y (RF) chain and one analog-to-digital converter (ADC) per antenna. The high cost and power consumption of RF chains and ADCs at mmWave frequencies make an all-digital processing approach prohibitive.When onl y a limited number of RF chains is available, h y brid architectures that split the precodinglcombining processing into the analog and digital domains are attractive. A previousl y proposed h y brid solution emplo y s phase shifters and mixers in the RF precodinglcombining stage. It obtains near optimal spectral efficiencies with a reduced number of RF channels. In this paper we propose a different h y brid architecture, which simplifies the hardware at the receiver b y replacing the phase shifters with switches. We present a new approach for compressed sensing based channel estimation for the h y brid architectures.Given the channel estimate, we propose a novel algorihtm that jointl y designs the antenna subsets selected and the baseband combining. Using power consumption calculations and achievable rates, we compare the performance of h y brid combining with antenna switching and phase shifting, showing that antenna selection is preferred in a range of operating conditions. I. INT RODUCTIONCommunication over millimeter wave (lmnWave) frequen cies [1] is the frontier for commercial wireless communication systems. Initial applications of mmWave to personal area networks (PAN) and local area networks (LAN) through the 60GHz unlicensed band are already standardized [2] and commercially available. The large bandwidths available at mmWave carrier frequencies also makes it interesting for 5G cellular systems [3], [4], [5], [6].MmWave communication requires very large multiple-input multiple-output (MIMO) systems to provide sufficient antenna aperture. Unfortunately, at mmWave there are additional hard ware constraints that have to imposed due to the practical limitations on the cost, complexity and power consumption with the current technology [7]. Due to mixed signal and baseband processing requirements, it may not be feasible to use one complete RF chain and one DAC or ADC per antenna, so precoding and combining can not be done entirely in the baseband. For this reason, systems like IEEE 802.11ad use analog beamforming / combining and only support single stream MIMO communication.of streams requires the use of precoding and combining, mak ing functions like low complexity and low overhead channel estimation more essential.In previous work, a hybrid architecture that accounts for hardware constraints has been proposed [8], [9], resulting in precoder/combiner design algorithms that divide the op timization process into the RF and the baseband stages, and channel estimation methods that exploit the sparse nature of the mmWave channel. This architecture is based on quantized phase shifters, as illustrate...

“…In this manor, a high gain and low power LNA is designed and implemented with more degree of freedom compared with the conventional designs. In [53], the transformer between the gate and the source of the first stage results in simultaneous input impedance and noise matching. For further reduction of the path losses between the input and the output of the LNA, the drain-source transformers replace the matching networks, which are consisted of thin film transmission line or lump components.…”

Abstract:In this paper, the advances of the silicon-based millimeter-wave (MMW) monolithic integrated circuits (MMICs) are reported. The silicon-based technologies for MMW MMICs are briefly introduced. In addition, the current status of the MMW MMICs is surveyed and novel circuit topologies are summarized. Some representative MMW MMICs are illustrated as design examples in the categories of their functions in a MMW system. Finally, there is a conclusion and description of the future trend of the development of the MMW ICs.

“…The total power consumption is 30 mW, since 26 mA from V G ¼ 700 mV and 10 mA from V DD ¼ 1.2 V are drawn. Table 1 shows the comparison between the measured performance of the presented design and the other recently published 60 GHz 90 nm CMOS LNAs ( [10][11][12][13][14][15]). It can be seen as our design is in line with the state of the art in LNA design.…”

The present paper presents a fully differential 60 GHz four stages low-noise amplifier for wireless applications. The amplifier has been optimized for low-noise, high-gain, and low-power consumption, and implemented in a 90 nm low-power CMOS technology. Matching and common-mode rejection networks have been realized using shielded coplanar transmission lines. The amplifier achieves a peak small-signal gain of 21.3 dB and an average noise figure of 5.4 dB along with power consumption of 30 mW and occupying only 0.38 mm 2 pads included. The detailed design procedure and the achieved measurement results are presented in this work.
