In this paper exact closed form expressions of the symbol error rate (SER) are derived for a quadrature phase-shift keying (QPSK) orthogonal frequency-division multiplexing (OFDM) system in presence of both residual carrier frequency offset (CFO) and symbol timing offset (STO). Analytical expressions for SER computation are given for transmission over additive white Gaussian noise and frequency selective Rayleigh fading channels. Enumerative results for each SER expression are given and verified through a comparison with Monte Carlo simulations.

Abstract

In this paper exact closed form expressions of the symbol error rate (SER) are derived for a quadrature phase-shift keying (QPSK) orthogonal frequency-division multiplexing (OFDM) system in presence of both residual carrier frequency offset (CFO) and symbol timing offset (STO). Analytical expressions for SER computation are given for transmission over additive white Gaussian noise and frequency selective Rayleigh fading channels. Enumerative results for each SER expression are given and verified through a comparison with Monte Carlo simulations.
