In a telecommunications system that employs frequency hopping techniques, network performance can be significantly improved by taking into consideration the level of interaction (e.g., the collision rate) between frequency hopping sequences, when allocating the frequency hopping sequences throughout the network. In a cellular network, this may be accomplished by deriving a network performance measure as a function of a current allocation of frequency hopping sequences for a number of cells and as a function of an expected collision rate (between the frequency hopping sequences) that appear for the current allocation. The frequency hopping sequences are then re-allocated amongst one or more cells until network performance is optimized. The allocation of frequency hopping sequences that results in optimized network performance may then be used for assigning frequency hopping sequences to new or existing connections (e.g., cellular calls) within a corresponding cell.

When communications of the same data are performed using a multi-carrier modulation method between a plurality of base stations and a mobile station at the same time and with the same frequency, a standing wave interference is generated to lower the carrier electric field level and the bit error rate is increased if the mobile station is located in an area where the reception powers of the electric waves from the base stations are almost identical. In order to prevent this, phase differences are set between the sub-carriers at the base station so as to enable the mobile station to avoid a situation in which all the sub-carriers are mutually cancelled. Thus, it is possible to easily correct an error, thereby improving the quality of communication.
