Coarse channel estimates are based on a time-domain correlation of a pseudo-random number ( PN) sequence with linear interpolation for the fine channel estimates over an OFDM block. 该方法使用伪随机(PN)序列时域相关进行信道粗估计,并在一个OFDM块内进行线性内插得到整个OFDM块内的信道细估计。
The PRFM pulse sequence is composed by 16 fixed-width and fixed-amplitude short pulses, in which the duration between two neighboring pulses is determined by pseudo-random number sequence. 此序列由16个固定宽度的高电平脉冲组成,两个相邻脉冲之间的低电平时间间隔是由伪随机数序列决定的。
In this paper, a universal mathematics expression for capture time in prediction circuit catching pseudo-random number sequence is established. 本文提出了序列予报捕获环搜捕时间的普遍表达式。
