Description: Euler方法 用C语言实现，并求解常微分方程组-The m framework appropriately generalizes notions such as gain margin, phase
margin, disturbance attenuation, tracking, and noise rejection into a common
framework suitable for analysis and design, in both single-loop and multiloop
feedback systems. Even when working with single-loop feedback systems, some
multi-input, multi-output (MIMO) systems arise during the analysis. Hence, a
unified framework to deal with MIMO linear systems is important, with full
support for both the time and frequency domain. m-Tools provides the
capability to build complex interconnections (such as cascade, parallel, and
feedback connections), compute properties (such as poles and zeros), calculate
time and frequency responses, manipulate these responses (FFT for the time
domain signals, Bode analysis for the frequency domain functions), and plot
results. m-Tools supports two data types in addition to the standard matrices:

Description: In this paper, we present a novel data-based method for simultaneous Maximum Likelihood
(ML) symbol and carrier-frequency o畇et estimation in Orthogonal frequencydivision
multiplexing (OFDM) systems. Statistical properties introduced by the cyclic
pre痻, a guard space between OFDM symbols, provide su眂ient information about the
unknown parameters. It is shown that the redundancy introduced by this cyclic pre痻
allows the estimation to be performed without additional pilots. Simulations show that
the performance of the frequency estimator is applicable in a tracking mode while the
timing estimation can be used in an acquisition mode. Platform: |
