Future flexible transceivers will be able to adjust modulation format, number of subcarriers, symbol rate, and forward error correction (FEC) scheme, according to channel and network conditions. This paper uses a combination of theoretical derivations and experimental results to recommend the best set of parameters to satisfy a specific demand to be routed along the network. In particular, for a given...

We study the energy consumption of wireless sensor network links applying three widely used digital modulation schemes, i.e. MQAM, MPSK, and noncoherent MFSK. For MQAM and MPSK, pulse shaping is considered. Both transmitted signal power and circuit power are taken into account where the former is modeled using the relationship between cutoff rate and signal-to-noise ratio (SNR) and the latter is modeled...
We study the energy consumption of individual links in wireless sensor networks (WSN). Three widely used digital modulation schemes, i.e. MQAM, MPSK, and MFSK, are analyzed and compared. Both transmitted signal power and circuit power consumptions are considered. For modeling the signal power, we use the relation between channel capacity or cutoff rate and signal to noise ratio (SNR). By numerical...
Much work has been done aiming at minimization of energy consumption for transmission of information in energy constrained wireless networks. However, most of them assume uncoded system, not considering the effect of channel coding. In this paper, using the relation between channel capacity or cutoff rate of MQAM modulation in AWGN channel and signal to noise ratio (SNR), we formulate the problem...
In this paper we propose an algorithm for high-resolution, joint azimuth, elevation and polarization estimation using polarimetric arrays of arbitrary geometry. The array elements may be placed on a planar or conformal surface and all the array imperfections are considered jointly. In particular, we focus on real-world arrays with imperfections. The Crameacuter-Rao Lower Bound (CRLB) for polarimetric...
