Abstract
Orthogonal Frequency Division Multiplex (OFDM) systems are very sensitive to phase noise caused by oscillator instabilities. In this paper the phase noise is resolved into two components, namely the Common Phase Error (CPE), which affects all the subchannels equally and the Inter Carrier Interference (ICI), which is caused by the loss of orthogonality of the subcarriers. We present a technique to estimate and correct the CPE component and demonstrate its effectiveness when applied to a Broadband Fixed Wireless Access (BFWA) data transmission system for the Multichannel Multipoint Distribution Service (MMDS) band. We show a performance increase up to 6 dB when applying the CPE correction in terms of the tolerance to the # .
