    摘要： A transmitter for a mobile communication system based on an OFDM scheme and a method for controlling the same. The transmitter can implement a characteristic of a multiple access scheme based on an OFDM scheme, a characteristic of a CDMA scheme, and a characteristic of a frequency hopping scheme which has very strong resistance to the frequency selective fading. An apparatus for transmitting information bit sequences from a BS (Base Station) transmitter to different users, includes a plurality of channelizers for dividing a single frame of information bit sequences to be transmitted to individual users into a plurality of times according to a given time interval, simultaneously transmitting the information bit sequences to the individual users within the plurality of division times, dividing the information bit sequences, spreading the divided information bit sequences using different Walsh codes, converting the spread information bit sequences into a single sequence associated with the individual users, and outputting the single sequence; and a frequency hopper for dividing the single sequence, distributing the spread information bit sequences over a plurality of bandwidths capable of mapping-processing the spread information bit sequences with sub-carrier frequencies, and preventing each of the bandwidths from overlapping with time-frequency cells given by the given time interval.

    摘要： An apparatus and method for reducing a Peak to Average Power Ratio (PAPR) in a broadband wireless communication system. A transmitter classifies symbols into full-symbols and sub-symbols, and divides a transmission full-symbol into at least two sub-symbols and transmits the sub-symbols, when the transmission full-symbol has a PAPR larger than a threshold set in the system. A receiver checks a transmitted symbol, determines if a full-symbol or a sub-symbol has arrived, and outputs a data when the full-symbol has arrived.
