摘要:Abstract(#br)In this paper, we introduce a new metric, namely, effective area spectral efficiency (EASE), to quantify the spectral efficiency as well as the spatial properties of point-to-point transmission systems and decode and forward (DF) relaying communications networks with...

摘要:... Our design objectives include both spectral efficiency and energy efficiency. In particular, we first derive the closed-form expression of the mean square error (MSE) which includes the impact of transceiver impairments. Based on that, we propose an alternating optimization a...

摘要:... The main purpose of the paper is maximizing the spectral efficiency of the system, which is reduced by using half-duplex relaying, while the bit error performance is kept below an appropriate threshold. The source transmits its data adaptively using quadratic amplitude modula...

摘要:Abstract(#br)Recently the energy efficiency (EE) in wireless communication is becoming one of the key performance metric for wireless communicating systems. For battery driven system like wireless sensor networks and ad-hoc networks, the energy conservation is a critical factor...
