Abstract:
1. A frequency hopping method in an OFDM (orthogonal frequency division multiplexing) system, comprising: (a) detecting a mutual interference degree between different cells, and determining whether to use a different frequency hopping pattern for each of the different cells for interference averaging according to the mutual interference degree; (b) determining a number P of the different frequency hopping patterns needed for satisfying the results of (a) between all the cells in the system; (c) generating the frequency hopping patterns of at least the number P determined in (b), and allocating one of the generated frequency hopping patterns to each cell in the system so as to satisfy the results of (a), (d) frequency-hopping the channels in each cell according to the frequency hopping pattern allocated in (c).
