Abstract

In this chapter, methods of dealing with the non-ideality of the radio over fiber infrastructure are described. Two general problems and their solutions are addressed: first, the nonlinear behavior of the radio over fiber links, dealt with through baseband compensation; second, the impact of fiber as well as propagation delays to the system performance. The compensation results show that the nonlinear distortions can be considerably reduced by low complexity predistortion. The timing delay analysis reveals that, particularly in OFDM based cellular wireless transmission setups with joint signal processing, the impact of the inter-symbol interference caused by transmitters with a large time difference of arrival only becomes critical if the system operates at a high SNR. Dependent on the pathloss environment and the cyclic prefix length, in the systems investigated, the additional asynchronous interference is rapidly attenuated so that it is almost not noticeable.
