Summary

The fifth chapter, deals with the Impact and Digital Suppression of Oscillator Phase Noise in Radio Communications, and is authored by Mikko Valkama, and Ville Syrjälä, from Tampere University of Technology, Finland, and Risto Wichman, and Pramod Mathecken from Aalto University, Finland. The design of compact and low-cost radios with high performance and reconfigurable capabilities is a challenging task due to the contradictory nature of these requirements, and is further hindered by the various imperfections and impairments of the analog electronics involved in the radio transceiver. Such imperfections are: mirror-frequency interference due to I/Q imbalance, non-linear distortion due to mixer and amplifier nonlinearities, timing jitter and non-linearities in sampling and analog-to-digital (A/D) converter circuits, and oscillator phase noise. These impairments can easily become a limiting factor in the performance of the radio device, especially when complex high-order modulated waveforms such as Orthogonal Frequency Division Multiplexing (OFDM) are being deployed. This chapter concentrates on phase noise, which has a complicated character and a large impact in the performance of multicarrier OFDM systems. A model of time-varying phase noise for free running and phase locked loop oscillators is presented, followed by a detailed description of the effects of phase noise in OFDM systems and time varying channels. Finally, different algorithms for the compensation of phase noise in digital base band, are explored.
