Abstract:
Presented is an efficient bandwidth determination model for the cognitive
positioning system by utilising multiple receive antennas. The
performance evaluations of the proposed multiple receive antenna
positioning system were carried out using the linear least squares
and maximum-likelihood location estimation techniques. Simulated
results reveal that in a rural scenario, the 1 × 2 and 1 × 3 singleinput-
multiple-output (SIMO) cases display an average bandwidth
efficiency with respect to positional accuracy, of 49 and 58%, respectively,
over the single-input-single-output (SISO) case. For an urban
scenario, the 1 × 2 and 1 × 3 SIMO cases display a higher average
bandwidth efficiency of 53 and 62%, respectively, over the SISO case.
