摘要

To achieve high-performance cell identification detection with low complexity for orthogonal frequency division multiplexing (OFDM) systems, this work proposes an efficient non-coherent cell identification (ID) detection technique based on a new optimization metric. Furthermore, the metric is simplified to two lower-complexity metrics. As such, two more modified cell ID detection methods extended from the first one are also proposed. Experiments show that all the three new cell ID methods achieve better performances than the conventional methods in multipath Rayleigh fading channels. This work also conducts the statistical analysis to characterize the proposed techniques completely. It is shown that the results of the theoretical analysis are close to the simulation results. Among the new techniques, specifically, the third proposed method using the second simplified new metric has much lower complexity and higher performance than the conventional methods.
