Patent Details

Applicant:
Indian Institute of Technology (IIT) Roorkee 
Title:
A digital transmitter with reconfigurable multi-carrier delta sigma modulation scheme and augmented noise shaping for concurrent multiband transmission 
Inventor(s):
Karun Rawat and Nishant Kumar 
Applicant:
Indian Institute of Technology (IIT) Roorkee 
Application type:
Applied - 2018-10-12 
Application Number:
201811038732 
Applied at:
India 
Entered by:
Indian Institute of Technology (IIT) Roorkee 
Abstract:
The present invention provides reconfigurable digital transmitter for future cellular or wireless communication with transmission in intra-band and inter-band carrier aggregation scenario. A reconfigurable transmitter is provided to transmit concurrently multi-carriers of different bandwidths, different modulation standards and tune the centre frequency of each carrier as per availability of the free spectrum. Delta sigma modulator converts envelope varying signal into constant envelope signal, which operates power amplifier near saturation resulting into high efficiency operation at amplification stage of transmitter 

 
THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
