本文将沃尔什函数与方块脉冲函数的构造方法相结合,导出了一种介于沃尔什函数和方块脉冲函数之间的三值函数——桥函数,可以证明,在一定条件下桥函数具有正交性,根据其正交条件可以从桥函数中导出许多完备或不完备的正交函数系。应用正交分割定理,本文提出了以桥函数为数学基础的遥测系统,并从理论上对其有效性和可行性进行了分析和论证。
In this paper, the Walsh function is combined with the construction method of the square pulse function to derive a three-valued function-bridge function between the Walsh function and the square pulse function. It can be proved that under certain conditions the bridge function Has orthogonality, according to its orthogonal conditions can be derived from the bridge function many complete or incomplete orthogonal function. Applying the orthogonal partition theorem, this paper proposes a telemetry system based on the bridge function, and analyzes and verifies its validity and feasibility theoretically.
