Analysis of Frequency Hopping Patterns for EUTRA Uplink

This paper describes the exploration of Frequency Hopping technique for the E-UTRA Uplink. The Frequency Hopping technique based on orthogonal hopping patterns can improve communication performance in a cellular system since it could make intra-cell interference be zero due to the orthogonality between sub-carriers in the same cell and average inter-cell interference. In this paper, a RB (Resource Block) adaptive hopping method based on predefined pattern of intra/inter-TTI frequency hopping is proposed for E-UTRA uplink, and both the Latin Square and the Welch-Costas array are derived for the method. Simulation results show that the proposed hopping mode is effective. We also simulate and analyze the impacts of the channel environment and parameters, the hopping pattern and frequency diversity on the performance of the DFT-SOFDM system.
