    • A transmitter and a transmitting method in a code division multiplexing (CDM) wireless communication system are provided. The transmitter includes a DC offset unit, a Barker code generating unit, a multiplier, a unipolar code generating unit, a Kronecker product unit, and a modulator. The DC offset unit transforms digital transmitting data to bipolar data, and the Barker code generating unit generates a Barker code. The multiplier multiplies the bipolar data with the Barker code and outputting the multiplying result, and the unipolar code generating unit generates a predetermined unipolar code. The Kronecker product unit multiplies the multiplying result from the multiplier and the unipolar code based on the Kronecker product, and outputs the result thereof, and the modulator modulates the output of the Kronecker produce unit through the On-Off keying modulation scheme.
    • 提供了一种码分复用(CDM)无线通信系统中的发射机和发射方法。 发射机包括DC偏移单元,Barker码产生单元,乘法器,单极码产生单元,Kronecker乘积单元和调制器。 DC偏移单元将数字发送数据变换为双极性数据,而Barker码生成单元生成Barker码。 乘法器将双极数据与巴克码相乘并输出乘法结果,单极码产生单元产生预定的单极性码。 Kronecker乘积单元乘以乘法器的乘法结果和基于Kronecker乘积的单极码,并输出其结果,并且调制器通过开 - 关键控调制方案调制Kronecker产生单元的输出。
