Abstract
In this thesis, error performance of spectrally precoded OFDM with frequency offset and Wiener phase noise is analyzed on AWGN channel, delay spread channel, flat fading Rayleigh channel, and two ray fading channel, with the help of Beauliu series. Characteristic functions on specific channels are derived upon which exact error probability is given for frequency offset case. A Gaussian approximation is made while dealing with the Inter-Carrier Interference (ICI) caused by Wiener phase noise.
ICI degrades the performance of OFDM system. Comparing average symbol error probability between spectrally precoded OFDM and uncoded OFDM is presented. Since spectrally precoded OFDM has higher spectral efficiency, we tend to examine whether the degradation of spectrally precoded OFDM is less than uncoded OFDM.
