Phase Noise in Asynchronous SC-FDMA Systems: Performance Analysis and Data-Aided Compensation

Analytical Performance Evaluation of SC-FDMA Systems in the Presence of Frequency and Time Offset

“…The main difference between this paper and [19]- [21] is that our work considers frequency offset and time offset while the mentioned papers evaluate the performance of a perfectly synchronized SC-FDMA system. What distinguishes [14] from our paper can be summarized as follows. The main goal of [14] is to compare the robustness of different mapping schemes when the system is hit by phase noise and CFO.…”

“…What distinguishes [14] from our paper can be summarized as follows. The main goal of [14] is to compare the robustness of different mapping schemes when the system is hit by phase noise and CFO. The authors of [14] also design a joint decoding and phase noise compensating method with reasonable complexity.…”

“…Investigating synchronization issues in SC-FDMA systems has motivated a vast amount of research [10]- [14], [16], [17]. For instance, the authors of [10] consider an SC-FDMA system hit by carrier frequency offset (CFO) and propose a receiver which jointly equalizes the signal in the frequency domain based on minimum mean square error (MMSE) criterion and compensates for the CFO.…”

“…The authors of [13] also evaluate the performance of their proposed method in the presence of CFO. In [14], an SC-FDMA system impaired by CFO and PN is considered and the authors propose an iterative phase noise compensator with reasonable complexity. This method does not transmit any pilot signals and uses estimates of the transmitted symbols in the receiver to estimate CFO and PN.…”

“…However, such analysis is of vital importance and facilitates fast and efficient design of SC-FDMA systems. One of the analytical works on this subject is [14] which considers an SC-FDMA system impaired by CFO and PN in which an expression for NMSE is derived. Another work on this subject is [18] which evaluates signal to interference plus noise ratio (SINR) in the presence of phase noise in SC-FDMA systems.…”
