An Exact Analysis of Oscillator Noise in M-QAM-OFDM Communication Systems

M. H. Madani, A. Abdipour, and A. Mohammadi
Abstract— This paper presents an exact analysis of noise effects of RF oscillators in M-QAM Orthogonal Frequency Division Multiplexing (OFDM) Communication Systems. The phase noise and the amplitude noise effects are studied in the performance of OFDM systems. A theoretical analysis for signal to noise degradation caused by phase and amplitude noise in OFDM bandwidth is presented. It is shown that bit error rate of analytical results is closely match with simulation results for OFDM system using M-QAM modulation.

Index Terms— OFDM, QAM, oscillator noise, signal to noise degradation.
