Introduction

Software-Defined Radio (SDR) Forum defines SDR technology as radios that provide software control of a variety of modulation techniques, wide-band or narrow-band operation, communications security functions (such as hopping), and waveform requirements of current & evolving standards over a broad frequency range.

In a nutshell, Software-Defined Radio (SDR) refers to the technology wherein software modules running on a generic hardware platform consisting of DSPs and general purpose microprocessors are used to implement radio ....etc

I am Dibash Bordoloi,a student of B.E final semester.I want the documents of the topicOptical serial to parallel conversion technique with phase shifted preamble for optical label switching systems.So, I want the documents of the topic to make my seminar report.
The abstract is:
Abstract—We have investigated the fundamental operation of
optical serial-to-parallel converter (OSPC) scheme with phaseshifted
preamble, and its application to optical label switching
operation. The OSPC consists of a π/2 phase-s ....etc

Preamble-based SNR Estimation in Frequency Selective Channels for Wireless OFDM Systems
AIM:
To develop an efficient algorithm for the average SNR estimation in wireless OFDM systems.
BACK GROUND:
• OFDM is a multicarrier modulation scheme that provides strong robustness against inter symbol interference (ISI) by dividing the broadband channel into many narrowband sub- channels in such a way that attenuation ....etc

Introduction:
In this 21st century we required a multi functional system to operate on different platforms, which can access data easily, the main purpose of a Heterogeneous server is to establish a Heterogeneous network that can connect computers and other devices with different operating systems and/or protocols. For example, local area networks (LANs) that connect Microsoft Windows and Linux based personal computers with Apple Macintosh computers are heterogeneous. The word heterogeneous network is also used in ....etc

Preamble-based SNR Estimation in Frequency Selective Channels for Wireless OFDM Systems
Synopsis
Introduction
There are two general categories of average SNR estimators. Data-aided (DA) estimators are based on either perfect or estimated knowledge of the transmitted data. However, a certain portion of data is needed for estimation purposes, which reduces bandwidth efficiency. Blind or in-service estimators derive SNR estimate from an unknown information-bearing portion of the received signal preserving efficiency a ....etc

Software-Defined Radio (SDR) refers to the technology wherein software modules running on a generic hardware platform consisting of DSPs and general purpose microprocessors are used to implement radio functions such as generation of transmitted signal (modulation) at transmitter and tuning/detection of received radio signal (demodulation) at receiver.

A Software Defined Radio (SDR) system is a radio communication system where components that have typically been implemented in hardware (i.e. mixers, filters, amplifiers, modulators/demodulators, detectors. etc.) are instead implemented using software on a personal computer or other embedded computing devices. While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics are making practical many processes that were once only theoretically possible. A basic SDR may consist of a computer (PC) equipped with a sound ....etc
