块式数据检测技术中的观测空间问题

Observation Space of the Block Data Detection Technique

根据短波信道的特点,抗多径干扰是主要的一个议题,由多径效应引起的码间串扰严重影响了短波数据传输的质量,所以有效的消除码间串扰非常重要。这里提出一种块式数据检测技术观测空间的选择方法,可以充分地利用已知信息,取得较好的检测效果。

Characteristics of shortwave channel is a primary topic to resist the multipath interference. ISI caused by the multipath effect severely affect the quality of shortwave data transmission and eliminate ISI is important. The paper provides a method of obser. vation space of the block data detection technique that can fully use the given information and the method are proved obtaining a better effect.
