“…In space antenna diversity, several antennas separated in space are used for reception of the transmitted signal. The basic idea behind the concept is that the received signals on different antennas are statistically independent (or at least highly uncorrelated) and therefore there is a good chance that they will not all be fading at the same time [5,8]. In dual space antenna diversity system, the dual diversity structure has two receiver sections that process the incoming signals independently.…”

“…Among many diversity techniques, the space-diversity reception in which vertically separated antennas are used to obtain diversity signal is very suitable for the millimetre-wave band. Since the wavelength of the millimetre-wave band is very short, many antennas can be designed to fit on small surface of the hand-held units [5]. Another countermeasure is adaptive equalization which corrects time dispersion caused by the channel and the intersymbol interference (ISI) [6][7][8].…”

SUMMARYWideband communication characteristics of wireless indoor millimetre-wave channel for arched and rectangular buildings are investigated. The impulse responses of arched and rectangular buildings for any transmitter-receiver location are computed by shooting and bouncing ray/image (SBR/Image) techniques. By using the impulse responses of these multipath channels, the impact of shapes of building is presented and the bit error rate performance of binary phase shift keying (BPSK) system with phase and timing recovery circuits are also calculated. Moreover, dual space antenna diversity technique and decision feedback equalizer (DFE) with four forward and three feedback taps are used to combat the multipath fading. Numerical results show that the mean root mean square (rms) delay spread for the arched building is smaller than that for the rectangular building. In addition, it is also found that the transmission rate can be up to 20 Mbps for indoor millimetre-wave channel of these two buildings by using dual space diversity and DFE.

“…Among them, mm-wave communication is widely considered a promising method as it can provide a wide available bandwidth [1][2][3][4] . Compared with other lower-frequency bands (e.g., microwave band), mmwave channels may experience much higher path loss [5,6] .…”

Millimeter wave (mm-wave) communication is widely considered to be a promising technique for 5G (Fifth Generation) cellular systems. Owing to the high path loss of mm-wave channels, 5G networks could employ a heterogeneous structure that consists of an MBS (Macro Base Station) and numerous SBSs (Small Base Stations). In this paper, we analyze the coverage and rate performance of an mm-wave heterogeneous network. Using user beam selection, we derive analytical expressions for the coverage probabilities of the SBSs and MBS. Furthermore, the average achievable rate for a typical user is also investigated. It is shown that the analytical results closely follow those of the simulations with marginal differences.

“…In general, the more available diversity branches, the larger the potential diversity benefit, and as a consequence a wide range of important emerging wireless communication systems (such as wideband CDMA and UWB systems [1], [2], [3], millimeter-wave (MM) systems [4], and multiple-inputmultiple-output (MIMO) systems [5]) tend to rely on physical layer solutions operating in diversity-rich environments, i.e. with a large number of diversity branches (L >> 1).…”

Traditional fading mitigation techniques are designed relative to the worst-case channel conditions, resulting in a poor utilization of the spectrum and the available power a good percentage of the time. In contrast, we introduce and investigate in this paper new adaptive modulation and diversity combining techniques that jointly select the most appropriate constellation size and the most suitable diversity branches in response to the channel variation and given a desired bit error rate (BER) requirement. Numerical results show that these newly proposed adaptive modulation and combining schemes can reduce considerably the average receiver channel estimation complexity as well as the power drain from the battery while offering high spectral efficiency and satisfying the desired outage probability and BER requirements.
