Innovation Net Accumulation Sequential Estimation for Sequence Acquisition
摘要
Abstract
The existing sequence acquisition algorithms repeatedly accumulate the foretime wrong information. Thus, their performance is poor in low SNR and high BER environment,especially when the sequence initial state is unknown.The paper presents a new method,INASE (Innovation Net Accumulation Sequential Estimation) for sequence acquisition.By designing innovation net accumulating scheme, the useful information can be accumulated more effectively.The comparison between INASE and the existing algorithm shows that INASE has better performance and can successfully acquire the PN sequence even in extreme bad communication environment.关键词
