Wireless communication is susceptible to eavesdropping attacks because of its broadcast nature. This paper illustrates how interference can be used to counter eavesdropping and assist secrecy.

The main paradigm of the 3GPP LTE network is to build a cellular network in which the core network is not aware of the radio access network.

This paper gives an overview on the possibilities and potential of dynamic vertical beamsteering in a cellular mobile radio system with focus on the interference limited macro-cell scenario.

Multiple transmit and receive antennas can be used to increase the number of independent streams between a transmitter receiver pair, and/or to improve the interference resilience with the help of

We address the problem of interference aware routing in multi-radio infrastructure mesh networks wherein each node is equipped with multiple radio interfaces and a subset of nodes serve as Internet

We demonstrate an improved micro-optomechanical spectral equalizer with more than 20 dB dynamic range over a 42 nm spectrum, less than 8 dB loss, reduced drive voltage, and a ruggedized opti-mechan

Satellite systems will of necessity use ground transmitter powers of several thousand watts.

A novel hybrid OFDMA/CDMA multiple access system for uplink communications in evolving 4G wireless systems is developed.

The problem of antenna array interference cancellation in an OFDM system is addressed. Joint estimation of the weight coefficients for all subcarriers is exploited.
