In this paper, the authors derived the analytical bit error rate expressions for orthogonal frequency division multiple access and single-carrier frequency-division multiple access (SC-FDMA) in Rayleigh slow-fading channel for binary phase-shift keying/quadrature phase-shift keying/16-quadrature amplitude modulations under pilot jamming and pilot symbol-assisted channel estimation. Beginning with the bit error rate analysis from the general case of pilot symbol-assisted channel estimation technique in Rayleigh slow-fading channel, the expressions are first modified for different modulations and then further customized to account for the Zero-Forcing equalization in frequency or time direction with application respectively to orthogonal frequency division multiple access or SC-FDMA without and with pilot jamming. Piecewise-linear interpolation is used for its simplicity. The simulation results match perfectly with the theoretical predictions except for some discrepancies with SC-FDMA, which imply that the generalized equations developed here have to be further modified to account for system-specific features like discrete Fourier transform precoding for SC-FDMA.
