Orthogonal frequency-division multiplexing (OFDM) chirp waveforms are an attractive candidate to be a dual-function signal scheme for the joint radar and communication systems. OFDM chirp signals can not only be employed to transmit communication data through classic phase modulation, but also can perform radar detection by applying linear frequency modulation for subcarriers. However, the performance of the OFDM chirp communication system under the phase noise environment still remains uninvestigated. This paper tries to discuss the influence of phase noise on OFDM chirp communication systems and proposes effective phase noise estimation and compensation methods. We find that the phase noise effect on OFDM chirp communication systems consists of a common phase error (CPE) and an inter-carrier interference (ICI). If not compensated, the performance of the dual-function systems can be seriously degraded. In particular, an exact expression for the signal-plus-interference to noise ratio (SINR) for the OFDM chirp communication system is derived and some critical parameters are analyzed to exhibit the phase noise effects on system performance. Moreover, two low-complexity estimation approaches, maximum likelihood (ML) and linear minimum mean square error (LMMSE), as well as two compensation approaches, the de-correlation and cancellation algorithms, are respectively utilized to eliminate the phase noise impairment. Finally, the phase noise effects and the effectiveness of the compensation approach are verified by extensive numerical results.

“…The cancellation method can avoid the operation of matrix inversion. Firstly, we can rewrite (30) in the following form Y = p0 HX+ Ŵ(1) P(1) +Z, (36) where p0 is the CPE factor which can be obtained by ML estimation. The matrix Ŵ(1) equals to the matrix Ŵ in (23) with the first column deleted.…”

“…In this study, linear complex field code is used as a transmit diversity scheme. In the same year, the effect of phase noise for Alamouti SFBC‐OFDM system was analyzed in the work of Kim and Kim . The use of correlative coding was demonstrated to reduce ICI, and numerical results were provided in form of carrier‐to‐interference ratio and bit error rate (BER).…”

“…[1][2][3] A lot of work has been done on the performance analysis of SFBC-OFDM system over different fading channels. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] In the year 2002, Lu et al 2 proposed a low-density parity-check code-based space-time code OFDM system for correlated fading channels in which performance analysis was given in terms of outage probability and OFDM word error rate. The frame error rate and outage probability of binary phase-shift keying (BPSK) and quadrature phase-shift keying (QPSK) modulated space-time block code (STBC)-based and SFBC-based OFDM system was reported by El Gamal et al 3 The performance analysis of space-time coding was done in the work of Garg et al 4 with imperfect channel estimation in 2005.…”

In this paper, the performance of space‐frequency block code orthogonal frequency‐division multiplexing (SFBC‐OFDM) system is analyzed over different fading channels using a generalized approach. General closed‐form expressions of average bit error rate (ABER) are derived for SFBC‐OFDM system. Both M‐ary phase‐shift keying and M‐ary quadrature amplitude modulation techniques have been considered in this analysis. The effect of imperfect channel estimation on ABER is included while deriving the ABER expression. The derived expressions are applicable under any given fading conditions provided that the moment‐generating function of fading channel is known. Simulation results are provided to verify the numerical results obtained from the derived expressions.
