Lower and upper bound expressions for the penalty of hybrid diversity used with any two-dimensional (2-D) signaling constellation with polygonal decision regions are derived. Using these bounds with well-known results for maximal ratio combining, the error probability performance of 2-D signaling with hybrid selection/maximal ratio combining can be(More)
The performances of two signal-plus-noise (S + N ) selection diversity receivers employing noncoherent M -ary frequency shift keying (MFSK) in slow, flat, correlated Rayleigh and Rician fading channels are examined. The branches are assumed to be equally correlated for Rician fading. The correlation model for Rayleigh fading is more general than the equally(More)
The rapid development and miniaturization of sensor devices, and the recent advances in wireless communication and networking technologies, are allowing scientists and engineers to develop networks of small sensors that can be used to continuously monitor the health and stability of the environment we live in. Wireless Sensor Networks (WSNs) consist of a(More)
In hybrid selection/maximal ratio combining the receiver selects the L branches with the largest signal-to-noise ratios from N available diversity branches and performs maximal ratio combining. A penalty is incurred with respect to maximal ratio combining which can be defined as the increase in signalto-noise ratio required for hybrid combining to achieve(More)
