Advance Train Collision System Using ARM Microcontroller

Abstract

In this paper, we consider a joint beam forming, power, and channel allocation in a multi-user and multi-channel underlay multiple input multi outputs (MIMO) cognitive radio network (CRN). In this system, primary users’ (PUs’) spectrum can be reused by the secondary user transmitters (SUTXs) to maximize the spectrum utilization while the intra-user interference is minimized by implementing beam forming at each SU-TX. After Formulate process on CR Network We implement beam forming structure on particular user based particular distance analysis on SVD using receiver part of analysis. In our modification we implement on multi channel on multiple user analysis of relay path based through put rate analysis on CR network using MISO system on SVD with Comparison of semi definite relaxation approach analysis.
