A subspace based blind channel estimation approach for zero-padding single carrier frequency domain equalization ( ZP-SC-FDE) systems is presented, which estimates the frequency-selective channel blindly in the time domain, based on zero-padding technology.
补零单载波频域均衡系统的盲信道估计方法利用系统固有的补零信息,在时域实现了频率选择性信道基于子空间的盲估计。
In order to determine relative positions between satellites and the attitudes of satellite of formation constellation, like-GPS carrier phase was added in based on former study of states determination combining with carrier phase differential GPS ( CDGPS) and like-GPS ranging code.
为了确定编队星座的星间相对位置和卫星姿态,在原有联合GPS差分和类GPS伪距进行状态确定的研究基础上,进一步加入了类GPS载波差分信息。
