Abstract

This paper investigates the affect of a frequency offset on the bit error probability of pilot symbol assisted modulation in frequency non-selective slow Rayleigh fading. Traditionally, the Wiener filter is designed to estimate both the fading induced multiplicative distortion and the frequency offset. However, it is shown that altering the frame structure to include consecutive pilot symbols and compensating for the frequency offset prior to Wiener filtering greatly improves the system performance
