【摘要】 信道估计是多输入单输出系统中的一项重要工作,分析比较了信道估计误差对于三种多输入单输出系统(空时分组码系统、频域预均衡系统及最大范数复合信道传输分集系统)性能的影响.模拟结果表明最大范数复合信道传输分集系统可以有效抑制干扰,降低误码率,因此对信道估计的误差比较灵敏.更多还原

【Abstract】 Channel estimation is one of the most important tasks for multiple-input single-output(MISO)systems. The influences of channel estimation error on three MISO systems, i.e.,STBC MISO system, Pre-FDE MISO system and MNCC transmitting diversity MISO system are analyzed. Simulation results show that the last one which is most sensitive to the channel estimation error, can effectively suppress interference and thereby improve system performance.更多还原
