Development of a Sliding Mode Control System with Extended Kalman Filter Estimation for Subjugator

ARGS is a MATLAB program which demonstrates command line argument retrieval.In particular, ARGS is a demonstration of the NARGIN function, which counts command line arguments and the VARARGIN function, which allows the user to specify that a routine has a variable number of input arguments.

跳频通信中采用BPSK调制之后的信号输出(the output of the signal after using BPSK modulation in frequency hopping communications)

In this paper, we investigate the timing and carrier frequency offset (CFO) synchronization problem in decode and forward cooperative systems operating over frequency selective channels. A training sequence which consists of one orthogonal frequency-division multiplexing (OFDM) block having a tile structure in the frequency domain is proposed to perform synchronization. Timing offsets are estimated using correlation-type algorithms. By inserting some null subcarriers in the proposed tile structure, we propose a computationally efficient subspace decomposition- based algorithm for CFO estimation. The issue of optimal tile length is studied both theoretically and through simulations. By judiciously designing the tile size of the pilot, the proposed algorithms are shown to have better performance, in terms of synchronization errors and bit error rate, than the time-division multiplexing-based training method and the computationally demanding space-alternating generalized expectation-maximization
