概要

• 論文の詳細を見る

• This paper describes two dimensional(2D)equalization scheme of orthogonal coding multi-carrier CDMA for reverse link of mobile communication systems. The purpose of the 2D equalization is the reduction of Multiple Access Interference(MAI)which is caused by the random access and the different propagation path from each mobile station. The orthogonal coding multi-carrier CDMA multiplexes all mobile stations data by Code Division Multiplexing(CDM). The 2D coding scheme spreads a preamble signal at time(in subchannel signals)and frequency(between subchannel signals)domains. The 2D decoding scheme estimates transmission delay time and instantaneous fading freauency from preamble signal for individual mobile stations and compensate the received data using these estimation values to reduce MAI.
