Fourier split-step (FSS) solutions of the parabolic wave equation (PWE) represent wave fields in terms of plane wave decompositions. However, those field solutions are usually only valid in the air space above built-up terrain, whereas field predictions for modern wireless systems often require knowledge of the fields on a street level. Since FSS PWE solutions with large step sizes are ...

Fourier split-step (FSS) solutions of the parabolic wave equation (PWE) represent wave fields in terms of plane wave decompositions. However, those field solutions are usually only valid in the air space above built-up terrain, whereas field predictions for modern wireless systems often require knowledge of the fields on a street level. Since FSS PWE solutions with large step sizes are not applicable for field computations between irregular scattering obstacles such as buildings, this problem is overcome by a two-step approach combining the FSS solution of the PWE with ray optical techniques to compute the fields at ground level in wooded and urbanized areas. To account for the great variety of propagation effects in a statistical sense, direct rays, reflected rays, diffracted rays and attenuated rays at typical receiver locations are included into the considerations. Comparisons to a wide variety of measured data show that this two-step approach produces better results than state of the art semiempirical field prediction techniques.

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.
End‐to‐end wavelength division multiplexing (WDM) transmission consists of a transmitter, a transmission channel, and a receiver. The transmission channel in all relevant WDM applications consists of a silica single‐mode fiber (SMF). This chapter describes the different SMF types, and discusses the several functional stages of WDM transmitters and receivers. It focuses on the photodetectors (photodiodes) and the associated active electronics. In high‐speed WDM transmission, almost exclusively photodiodes are used as photodetectors. The chapter considers the commonly used PIN photodiodes and avalanche photodiodes (APDs). In order to increase the transmission distance or to allow other transmission impairments, forward error correction (FEC) can be applied to the signal. FEC allows the operation of the optical transmission at a higher BER, while maintaining payload data integrity. Electronic distortion compensation (e.g., CD compensation) is an alternative to analog optical compensation.

Two design methods of a filter in frequency-spatial frequency domain (f-k filter) have been developed for bistatic radar to suppress direct wave which causes significant artifacts in a radar image. One method is to reject a region in f-k domain, where the region is determined from a position information of a transmitter and a receiver. The other method uses time shift to eliminate a difference of arrival time of the direct wave. Then, f-k spectrum of the direct wave concentrates around frequency axis, and filter to reject DC component in spatial direction is designed. Both methods are verified with a laboratory measurement. They can suppress strong artifacts caused by the direct wave clearly, and give more reliable image to detect a buried object.
