It is desirable to replace such trial installations by computer simulations. We present in this paper an algorithm that allows a fast and interactive deterministic prediction of three-dimensional field strength maps. With this tool it is possible to quickly find an efficient placement of base stations for the required coverage in a building complex. The simulated environment is modeled as a large network of geometric channels that contain the propagated signal. The calculation of the local coupling between the channels can be carried out in advance because it does not depend on transmitter and receiver positions. In a second step, field strength maps are calculated interactively for arbitrary transmitter and receiver configurations based on the geometric information stored in the channel coupling coefficients. Since the concept of a channel network allows the implementation of global energy conservation, the prediction is expected to provide optimal robustness against details in the description of the building. This is demonstrated by the comparison of the predictions in different three-dimensional building structures to corresponding measurements of the fading-averaged field strength.","PeriodicalId":409898,"journal":{"name":"2000 International Zurich Seminar on Broadband Communications.

In contrast to the usual mini-max criteria, the l/sup 2/ criteria of goodness are used to assess correlation properties of spreading sequences. To motivate it, direct evidence is given to demonstrate the utility of the l/sup 2/ criteria in the context of CDMA performance. Following, these criteria are applied to two types of known unit-magnitude sequences: generalized binary Rudin-Shapiro sequences, and sequences with quadratic phase function. The construction rule of the well-known binary Rudin-Shapiro sequences is based on a recursion formula that starts with the Kronecker sequences. It is shown that the asymptotic limits (N/spl rarr//spl infin/) of l/sup 2/ criteria obtained for original Rudin-Shapiro sequences are also valid in case of two arbitrary sequences obtained by means of the same recursion formula as long as the initial sequences are complementary. As to the sequences with quadratic phase function, the upper and lower bounds on the inverse merit-factor are proved to decrease with the order /spl radic/N+1, which indicates excellent auto-correlation properties of the sequence.","PeriodicalId":409898,"journal":{"name":"2000 International Zurich Seminar on Broadband Communications.
