摘要： Provided is a radio communication base station device capable of acquiring both a multi-user diversity effect and a frequency diversity effect simultaneously in multi-carrier communications. In this device, modulation units (101-1 to 101-n) modulate data to mobile stations (MS#1 to MS#n) individually to create data symbols. A separation unit (102) separates each data symbol inputted, into an Ich (in-phase components) and a Qch (orthogonal components). An Ich arrangement unit (103) and a Qch arrangement unit (104) arrange the Ich and Qch, respectively, in a plurality of sub-carriers constituting an OFDM symbols, and output the same to a synthesization unit (105). This synthesization unit (105) synthesizes the Ich and Qch arranged for each sub-carrier, to create the synthesized symbol.

摘要： Provided is a wireless communication apparatus by which reduction of a diversity gain can be suppressed at minimum in the case of employing a repetition technology in multicarrier communication. In the wireless communication apparatus (100), repetition sections (102-1 to 102-n) repeat each data symbol inputted from modulating sections (101-1 to 101-n) to create a plurality of identical data symbols.

摘要： A multicarrier transmitting apparatus capable of improving the data symbol error rate characteristic to improve the reception quality. In this apparatus, a replacement position deciding part (141) decides, based on a number of replacements notified of by a scheduler (110), which one of a plurality of data symbols should replaced by a second pilot. Herein, a restricted condition, which is ‘RF after replacement is equal to or greater than RF before replacement minus one’, is satisfied. A replacing part (142) replaces, in accordance with the replacement position outputted from the replacement position deciding part (141), a part of the data symbols included in a repetition signal by a second pilot symbol, and outputs the resultant replaced signal to an IFFT part (105).
