“…Therefore, approximating the aggregate interference with a lognormal random variable does not seem to be a promising solution. Another alternative is logarithmic convolution to compute the PDF of a power sum of two random variables [11]. This method gives exact results for arbitrary distributions, but numerical integration is needed and it is computationally expensive.…”

The 3.5 GHz citizens broadband radio service (CBRS) band in the U.S. is a key portion of mid-band spectrum shared between commercial operators and existing federal and non-federal incumbents. To protect the federal incumbents from harmful interference, a spectrum access system (SAS) is required to use a common, standardized algorithm, called the move list algorithm, to suspend transmissions of some CBRS devices (CBSDs) on channels in which the incumbent becomes active. However, the current reference move list implementation used for SAS testing is non-deterministic in that it uses a Monte Carlo estimate of the 95 th percentile of the aggregate interference from CBSDs to the incumbent. This leads to uncertainty in move list results and in the aggregate interference check of the test. This paper uses upper and lower bounds on the aggregate interference distribution to compute deterministic move lists. These include the reference move list used by the testing system and an operational move list used by the SAS itself. We evaluate the performance of the proposed deterministic move lists using reference implementations of the standards and simulated CBSD deployments in the vicinity of federal incumbent dynamic protection areas.

“…The assumption of one user per channel is less valid for the outer ring than for the inner circle, but it is still good enough to use for the outer ring because these interferers have less influence than the interferers in the inner circle. The pdf for the total signal power received (rsp) by a PP on an arbitrary channel becomes rsp rsp (32) Equation (32) can be calculated with the convolution transformed for the logarithmic domain [16]. We will use the results of (32) in the next section to calculate the interference power on an arbitrary channel.…”

Abstract-Dynamic channel selection (DCS) is an algorithm for flexible resource sharing in mobile radio systems. The digital enhanced cordless telecommunications (DECT) standard implements a version of DCS based on time as well as frequency multiplexing. In this paper, mathematical models are developed to evaluate the probabilities of channel availability, desired carrier power, and the carrier-to-interference ratio (CIR) for a constant traffic load. These results can be used to compute the call setup blocking probability. The models reported in this study are based on a decentralized DCS according to the DECT standard specifications. The results show that blocking due to availability of a channel (resource blocking), not interference blocking, generally is the most important factor in overall call blocking. Furthermore, it is seen that the resource blocking is sensitive to the implementation of the portable sets. Also, with homogeneous static traffic, this type of DCS can be as good as fixed channel allocation (FCA) with respect to resource blocking.

This Chapter focuses on co‐channel interference in cellular TDMA networks. Both the generation of co‐channel interference and the appropriate interference suppression methods are considered. Contributions of frequency reuse,spatial filtering and time domain interference cancellation on the residual interference are described. Effects of variable propagation parameters (especially lognormal shadowing),cluster sizes and interference parameters to the outage probability are illustrated. Furthermore, the spectrum efficiency examples are shown in the form of the Erlang capacity at variable cluster sizes and quality‐of‐service criteria.
