— In this paper, we analyze the effects of IQ (In-phase/ Quadrature-phase) imbalances at both transmitter and receiver of OFDM (Orthogonal Frequency Division Multiplexing) system...
—This paper deals with the case of a high speed mobile receiver operating in an orthogonal-frequency-divisionmultiplexing (OFDM) communication system. Assuming the knowledge of d...
In this paper, we describe a digital scenario where we simulated the emergence of self-organized symbol-based communication among artificial creatures inhabiting a virtual world of...
