No full textIn this letter, we develop a robust and scalable
algorithm to cope with the sensor placement problem for target
location under constraints of the cost limitation and the complete
coverage. The problem is NP-complete for arbitrary sensor fields.
The grid-based placement scenario is adopted and the sensor
placement problem formulated as a combinatorial optimization
problem for minimizing the maximum distance error in a sensor
field under the constraints. The proposed algorithm is based
on the simulated annealing approach. The experimental results
reveal that, for small sensor fields, the algorithm can find the
optimal sensor placement under the minimum cost limitation.
Moreover, it can also find a placement with minimum distance
error for large sensor fields under the cost limitation

No full textA very low power consumption (6 mW) 5 GHz band receiver frontend
using InGaP-GaAs HBT technology is reported. The receiver
front-end is composed of a cascode low noise amplifier followed by a
double-balanced mixer with the RF transconductor stage placed above
the Gilbert quad for direct-coupled connection. The RF band of this
receiver front-end is set to be 5.2 GHz, being downconverted to 1 GHz
IF frequency. Input-return-loss (S11) in RF port smaller than 12 dB
and excellent power-conversion-gain of 35.4 dB are achieved. Input
1 dB compression point (P1dB) and input third-order intercept point
(IIP3) of 24 and 3 dBm, respectively, are also achieved
