The concept of interference alignment has been studied mainly from an information-theoretic and signal processing point of view, focusing on scenarios with a high degree of coordination among nodes often achieved by means of transmission scheduling. However, many real-world networks employ random access policies rather than deterministic scheduling, and it is therefore important to understand how...
The use of datalink communication in the VHF avionics band is increasing. This expansion increases the opportunity for interference between a datalink transmitter and a co-sited conventional AM type receiver for voice reception. The interference is audible by the pilot using the AM receiver and takes the form of periodic or aperiodic noise bursts or clicks heard over incoming voice traffic. Signal...
In this paper we discuss performance results of a novel real-time closed-loop power amplifier (PA) linearization technique that has originally been proposed by Ahmed and Li. The novel approach performs on-the-fly prediction and measurement of the PA AM/AM and AM/PM non-linearity, stores such non-linear characteristics and calculates their inverse functions in order to pre-distort the base-band amplitude...
The selective receiver structure which separates the received STBC (space time block coded) signals into the divided group was proposed. This method enables the decoding process to have no interference from the signals in different group. The simulation results shows that the newly proposed scheme can have better performance than the conventional receiver for the STBC signals
