Separation and Reconstruction Method of Mixed and Long Duration Communication Signals
In radio communication system,the mixed and long duration communication signals are split in time and separated block by block in the receiver.But the inherent uncertainty of separation causes the problem that the separated signals at adjacent blocks are not completely the same in permutation,amplitude and phase,which results in incorrect connection when the separated signals at adjacent blocks are tied together.To solve this problem,a separation and reconstruction method was proposed.Simulation experiments were designed to prove the method’s performance,which shows that,compared with the method based on associativity in column vectors of an estimated mixed matrix in [9],the proposed method has better performance.
Abstract : Volume I contains sufficient background material to put the work in perspective, summarizes the methodology used, and presents the study findings and implications for effective automation, as well as quantative capacity estimates and predictions. The methodology is based on a technique called the Relative Capacity Estimating Process (RECEP), developed to assess the implications of controller judgmental factors and decision processes for attainable capacity at several levels of automation. RECEP incorporates a technique of sector operational measurement that includes video recording and structured controller interviews. The technique has been applied to various types of transition, terminal interface, and en route sector operations in several FAA facilities. Results obtained include capacity estimates, for each of the airspace sectors studied, as operated at present and at several future levels of automation.
