Apart from providing high system capacity it is essential for mobile communications systems as UMTS to operate with low electromagnetic emission.
The main objective of this paper is to assess the performance improvements of practically applicable beamforming concepts for UMTS networks.
We consider the problem of characterizing per node throughput scaling in arbitrary extended wireless networks.
Given a continuous semiring A and a collection h of semiring morphisms mapping the elements of A into finite matrices with entries in A we define h-closed semirings.
Recently, broadband analog network coding (ANC) was introduced for high-speed transmission over the wireless (frequency-selective fading) channel.
In this paper, we analyze the bit error rate (BER) and mean square error (MSE) performance for data uplink of a multi-cell TDD system with imperfect knowledge of channel state information (CSI).
The sizes of the BGP routing tables have increased by an order of magnitude over the last six years.
Two-classes classification with partial statistics is studied for finite alphabet sources.
We study the domain of dominant competence of six popular classifiers in a space of data complexity measurements.
We discuss certain relations between cloning and the NOT operation that can be derived from conservation laws alone.
