数字无线通信系统和数字无线通信方式
摘要：
本发明涉及数字无线通信系统和数字无线通信方式。本发明的数字无线通信系统，QPSK调制用正交基带信号生成部(301)生成QPSK调制用正交基带信号。8PSK调制用正交基带信号生成部(302)生成8PSK调制用正交基带信号。同相分量切换部(304)和正交分量切换部(305)，根据调制方式确定信息对QPSK调制用正交基带信号、8PSK调制用正交基带信号以及导频码元进行切换，输出给无线部(306)。无线部(306)输出对基带信号进行规定的无线处理的发送信号。该发送信号由功率放大器(307)放大，由发送天线(309)输出经过放大的发送信号。因此，可同时考虑提高数据传送速度和终端便利性这两者。
摘要（英）：

The invention relates to digital radio communication system and digital radio communication mode. In the digital radio communication system, QPSK modulated quadrature baseband signal generating section 301 generates a QPSK modulated quadrature baseband signal. 8PSK modulated quadrature baseband signal generating section 302 generates an 8PSK modulated quadrature baseband signal. Based on the modulation scheme determined information, in-phase component switching section 304 and quadrature component switching section 305 switch between the QPSK modulated quadrature baseband signal, 8PSK modulated quadrature baseband signal and pilot symbol to output to radio section 306. Radio section 306 performs the predetermined radio processing on the baseband signal to output a transmission signal. The transmission signal is amplified in power amplifier 307, and the amplified transmission signal is transmitted from transmission antenna 309. It is thereby possible to take into account both the improvement in the data transmission rate, and the benefit and convenience in terminals.
