METHOD FOR HOPPING FREQUENCY IN OFDM SYSTEM

METHOD FOR HOPPING FREQUENCY IN OFDM SYSTEM

PURPOSE: A method for hopping a frequency in an OFDM system is provided to obtain the equalization of interference by maintaining constantly a degree of interference among channels within two adjacent cells. CONSTITUTION: A degree of mutual interference between different cells is detected(S1). The d...

description PURPOSE: A method for hopping a frequency in an OFDM system is provided to obtain the equalization of interference by maintaining constantly a degree of interference among channels within two adjacent cells. CONSTITUTION: A degree of mutual interference between different cells is detected(S1). The different hopping patterns between the cells is determined according to the detected degree of the mutual interference(S2). The number of the different frequency hopping patterns among all cells within a system is determined(S3). The frequency hopping patterns are designed(S4). The frequency hopping patterns are assigned to each cell(S5). The frequency hopping process for channels within each cell is performed according to the assigned frequency-hopping pattern(S6).
