Measurement of Signal Strength in CDMA by Simulation of Power Losses Estimation

Authors : Muhammad Rezaul Hoque Khan

Abstract: CDMA (Code Division Multiple Access) combines multiple signals and improves signal strength. This leads to the near elimination of interference and fading. Both electrical background noise (computer noise) and acoustic background noise (background conversations) are filtered out by using narrow bandwidth, which corresponds to the frequency of the human voice. This keeps background noise out of our conversations. In this paper a simulation of power lossess estimation is compared with real measurements. The field strength at corner points of each cell is calculated using modified Hata model based on reference regarding the antenna heights of the base station and mobile station at 30 and 1.5 meters and the antenna gain of the base station and mobile station at 17 dB and 0 dB respectively. Results obtained are compared with those of predicted by Citycell Digital, only CDMA operator in Bangladesh, first to adopt CDMA technology in the sub-continent. In this paper the experimental data collected through the area of coverage in different cases.
