| 摘 要： | 网格空时码是在时延分集的基础上与TCM编码结合而成的,是一种改进的传输分集方式,适用于多种无线信道环境。在无线通信中为了有效抑制噪音积累,选用QPSK调制,因为QPSK调制比QAM更适合噪音环境,QPSK调制具有理想的误差保护。网格空时码在QPSK调制传输系统中具有更好的纠错能力,具有低误码率与误帧率的优良性能。 |

| Abstract: | An improved transmit diversity mode for a variety of wireless channels, the space time trellis code is based on delay diversity combined with TCM code. QPSK modulation is used to suppress the noise accumulation due to the fact that it is more suitable for noisy environment than the QAM and that QPSK modulation possess ideal error protection. The STrC code in QPSK systems has better correction and lower bit error rate and block error rate. |
| Keywords: | space time trellis code bit error rate block error rate quadrature phase shift keying |
