A New Approach in Wirelss Communication: Design and Development of a Simulator For Receiver Processor

Abstract

In this paper we designed and developed a Simulator for radar receiver and transmitted sub system using VIRTEX5 FPGA Board. In this radar Receiver processor subsystem the function of the receiver processor is to accept different data parameters like Frequency, Amplitude, Direction Finding, Pulse Width and PRI presence pulses from different receivers. There is a need to test the receiver processor in standalone mode before integrating or comparing  it with the other receiver. The purpose of this simulator module is to design and develop a simulator based on VIRTEX 5 FPGA simulator board using RS232 serial communication link. The project is broadly segregated into two major activities which will be carried out in two methods. In stage I, a Graphical User Interface (GUI) is designed and developed based on  LABVIEW which provides the pulses parameters of intercepted pulse along with the parameter code using a computer. Next the selected code is encoded. Subsequently followed by sending of the coded data using an RS 232 serial link to the target hardware. The target hardware is a VIRTEX 5 FPGA based simulator board.

In stage II, firstly the coded data is decoded based on received parameter code. This activity is carried out by developing a code based on ‘C’ language using the hardcore power PC 440 processor available in the VIRTEX 5 FPGA in an embedded design environment. Subsequently followed by design and developed of digital glue logic which finally generates all the required parameter data like Frequency, Amplitude, Direction Finding, Pulse Width and PRI presence pulses for the received parameter code. This activity is carried out by developing a code using ‘Embedded C’ language.Finally all the developed code in phase II is tested for its complete functionality in the simulated environment. Subsequent to which the complete code is implemented on the target hardware board and testing will be carried out for the complete functionality using VIRTEX 5 FPGA Board.
