tools for DSR

Introduction

2. Motivation of SDR

  • Commercial wireless communication industry is currently facing problems due to constant evolution of link-layer protocol standards (2.5G, 3G, and 4G)
  • existence of incompatible wireless network technologies in different countries inhibiting deployment of global roaming facilities
  • problems in rolling-out new services/features due to wide-spread presence of legacy subscriber handsets.

Signal Processing Algorithms for SDR

  • Spectrum Signal Processing
  1. Software Architecture of SDR
  1. The system uses a generic hardware platform with programmable modules (DSPs, FPGAs, microprocessors) and analog RF modules. The operating environment performs hardware resource management activities like allocation of hardware resources to different applications, memory management, interrupt servicing and providing a consistent interface to hardware modules for use by applications.
  2. In SDR system, the software modules that implement link-layer protocols and modulation/demodulation operations are called radio applications and these applications provide link-layer services to higher layer communication protocols such as WAP and TCP/IP.
