To address the security and performance challenges, a novel smart grid communication system based on the Frequency-Hopping (FH) technology is investigated in this paper. A new FH sequence set with various levels of Hamming cross-correlation values is proposed for this system in order to endow the power users various Qualities of Services (QoSs). By using the real measurement, the authors propose a statistic model of the data collected from power grid. Based on the proposed FH sequence set and the data model, the analytic expression of the Bit Error Rate (BER) of such a system with Binary Frequency Shift Keying (BFSK) modulation is derived under slow Rayleigh fading channel model.
