Apparatus and method for transmitting and receiving data in a code division multiplexing-frequency hopping-orthogonal frequency division multiple access communication system

摘要

A system and method for transmitting data by a base station in a multiple access communication system including a plurality of sub-channels, each of which includes a predetermined number of sub-carrier bands, the sub-carrier bands being divided from an entire frequency band. The method includes the steps of: dividing input data streams in a unit of the sub-channels corresponding to each terminal into a plurality of data sequences based on a predetermined length; spreading each of the data sequences by a distinct spread spectrum code, respectively; summing and parallel-converting the spread data; hopping each frequency of the parallel-converted data in the unit of the sub-channels based on a frequency hopping pattern allocated to each of the terminals in advance; performing an inverse fast Fourier transform with respect to the hopped parallel-converted data; and transmitting the transformed data.
