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.
