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 multiplication of correlation could be implemented just by pseudo random gating sampling (analog) or data reservation control and rejection (digital).
相关处理乘法可简单地用伪随机门控采样(模拟)或伪随机控制数据保留与剔除(数字)方法实现。
Pseudo-random sequences with optimal properties such as correlation, high linear spans, balance and long period are widely used in CDMA system, spread spectrum and hopping communication systems.
具有优良相关性，大线性复杂度，平衡性，长周期的伪随机序列广泛应用于CDMA系统，扩跳频通信系统。
