“…Additionally, an exact and general closed form expressions for the BER of MPSK in the presence of a fixed phase error are provided in [38]. Also, accurate expressions for the bit error probability (BEP) of Gray-coded M-ary rectangular and square QAM in the presence of phase noise in both AWGN and fading channels are presented in [39]. The effect of Gaussian phase noise on various waveforms is investigated and digital modulations in presence of phase noise are compared in [40].…”

The size of the data transmitted in communication systems is constantly increasing and leads to the need for high bandwidth. Therefore, using the millimeter wave (mmWave) band is one of the best solutions in data transmission. Frequency multiplication via nonlinear components is used for signal generation at higher frequencies in the millimeter to submillimeter bands and it is of great importance in generating signals up to 2.2 THz. Although communication systems with the highest carrier frequency using these components are available at the 300 GHz-340 GHz, standard communication models do not comply with data transmission at this band, bringing problems caused by nonlinearity throughout data recovery. We solve these problems with the proposed constellation modification method, which has not been studied before. In this study, it is aimed to provide data transmission in the mmWave band with an experimental communication system that is compatible with the frequency multiplication and has high spectral efficiency. For the first time to our knowledge, a novel constellation modification method that can be modified according to the frequency multiplication on the standard M-ary phase shift keying (MPSK) data is proposed. In this method, the existing receiver structure is preserved and MPSK with harmonic modulation is carried. In the experimental demonstration part, harmonic binary shift keying (BPSK) data transmission via frequency multiplied 30 GHz transmitter was achieved with a power penalty of 2.3 dB, and this shows that MPSK data transmission over harmonic mmWave or submillimeter band sources is now possible.

“…These works illustrate that PN system performance degradation will be more significant in high band carriers. As well, the bit error probability (BEP) of M-QAM with PN under AWGN and flat-fading channels is studied in [58]. This work considers a PLL oscillator and derives the bit error floor (BEF).…”

Wireless transceivers for mass-market applications must be cost effective. We may achieve this goal by deploying non-ideal low-cost radio frequency (RF) analog components. However, their imperfections may result in RF impairments, including phase noise (PN), carrier frequency offset (CFO), and in-phase (I) and quadrature-phase (Q) imbalance. These impairments introduce in-band and out-of-band interference terms and degrade the performance of wireless systems. In this survey, we present RF-impairment signal models and discuss their impacts. Moreover, we review RF-impairment estimation and compensation in singlecarrier (SC) and multicarrier systems, especially orthogonal frequency division multiplexing (OFDM). Furthermore, we discuss the effects of the RF impairments in already-established wireless technologies, e.g., multiple-input multiple-output (MIMO), massive MIMO, full-duplex, and millimeter-wave communications and review existing estimation and compensation algorithms. Finally, future research directions investigate the RF impairments in emerging technologies, including cell-free massive MIMO communications, nonorthogonal multicarrier systems, non-orthogonal multiple access (NOMA), ambient backscatter communications, and intelligent reflecting surface (IRS)-assisted communications. Furthermore, we discuss artificial intelligence (AI) approaches for developing estimation and compensation algorithms for RF impairments.

“…Regarding the impact of phase noise on the bit-error rate (BER) performance, there has been a number of studies for Mary phase-shift keying (PSK) modulation (M -PSK) [1]- [3], and references therein. Remarkably, for the case of rectangular QAM, an exact closed-form conditional BER expression under AWGN channels has been reported very recently [4]where the derivation follows the similar approach presented in [5] for the case without phase noise. Specifically, exact expressions were derived for the first two bits of symbols on the I channel.…”

“…Although BRGC sequences are equivalent in terms of the BER, each gives rise to a particular characterization of bit decision regions and positions, resulting in a different closedform expression. Note that the authors in [4], [5] assumed the original BRGC sequence proposed by Frank Gray in [7] for their derivations.…”

“…This serves as the motivation for choosing the original BRGC sequence in our analysis. Unlike the previous works where closed-form expressions were obtained through generalization from specific cases [4], [5], our approach is to derive an exact closed-form expression for an M -PAM by analytically characterizing the bit decision regions and positions. The resulted expression can then be naturally applied to compute the conditional BER of a rectangular QAM conditioned on a given phase noise in Section III.…”

In this paper, we newly present a closed-form biterror rate (BER) expression for an M -ary pulse-amplitude modulation (M -PAM) over additive white Gaussian noise (AWGN) channels by analytically characterizing the bit decision regions and positions. The obtained expression is then used to derive the conditional BER of a rectangular quadrature amplitude modulation (QAM) for a given value of phase noise. Numerical results show that the impact of phase noise on the conditional BER performance is proportional to the constellation size. Moreover, it is observed that given a constellation size, the square QAM achieves the lowest phase noise-induced performance loss compared to other rectangular constellations.
