Abstract:This paper provides more prominence for the eNodeB to use reliable and robust algorithm for self configuration of the Neighbor Cell List (NCL). The novel NCL selection scheme is based on Potentially Worst case Carrier to Interference (PWCI) which, in contrast is more promising than the conventional Receive Signal Strength Indicator (RSSI) based cell identity detection of neighbor cells that maximizes the performance of the system. The proposed scheme utilizes the PWCI as a threshold for neighbor cell ID detection under high noise and interference scenario rather than the empirically generated RSSI threshold. Simulation results shows that proposed self configured NCL detection improves the performance rate by 7% and achieves the probability of right cell ID detection around 85% under noisy environment, moreover the success rate for the cell ID detection for fixed time offset and carrier frequency oscillation(CFO) at different cases also improved by about 20% based on the existing scheme.
