ABSTRACT: This paper introduces a novelty method of using a Linear Prediction
Coefficient (LPC) filter, a digital signal processing (DSP) tool to get
accurate signal measurement in noisy mobile environment. By measuring the
received power of a mobile radio, it also measures the coverage of an area
served by several base stations. For results’ validation, the mobile received
power at user end of two Code Division Multiple Acccess-2000 (CDMA2000) cellular
networks operating at different frequency (450 MHz and 800 MHz) in the same
environment, Lome in Togo, was considered. Our analysis has consistently shown
that within the problem areas in the coverage, the filter response does not
match with the measured data. These mismatching areas may likely result from
poor soft-handoff process or some dead zones. The study has proven the
significant help of this novelty method in problem areas identification.
Consequently, such a filter can be embedded to current firmware for Radio Frequency
coverage optimization, and for an effective spectrum efficiency.
