The Guest Lecture on ‘APPLICATIONS OF IoT IN BIO-MEDICAL ENGINEERING’

By MVJCE

The Guest Lecture on ‘APPLICATIONS OF IoT IN BIO-MEDICAL ENGINEERING’ was delivered by Mr. Narayanaswamy N C, Senior Team Lead, Ericsson Global India Services Pvt. Ltd., Bangalore. The event was attended by faculty and students of the Medical Electronics Department.

Mr. Narayanaswamy’s itinerary for the Lecture was as follows:

  • Introduction to IoT in HealthCare and Bio-Medical spheres
  • Applications of Signal processing
  • Introduction to GNSS domain
  • Hardware of GNSS receivers
  • Signal processing in GNSS receivers
  • Tracking algorithms in GNSS receivers
  • Other signal processing areas
  • Industry expectation of signal processing
  • Job opportunities
  • Q&A

Mr. Narayanaswamy opened the session with a brief introduction to Signal processing. Next, he spoke about Applications of Signal processing, Introduction to GNSS domain, Hardware of GNSS receivers, Signal processing in GNSS receivers, Tracking algorithms in GNSS receivers, Industry expectation of signal processing and job opportunities in the field.

Applications of signal processing:                

  • Telephones, CRT TVs, Radios, Antennas, Cameras
  • Mobiles, LCD/LED TVs, MP3 players, STB, Digital Cameras
  • Cloud based solutions
  • Communication systems for the armed forces
  • Tracking devices for aircrafts, trains, cars and buses
  • Measurement devices, Oscilloscopes, Network Analyzers, Signal Generators

Signal processing in GNSS:

IF = Carrier (down-converted) x Code x Data
I-phase = IF x Carrier (local) x Code (local)
Q-phase = IF x Carrier (local – 90) x Code (local)
Early, Prompt, Late

Tracking loops in GNSS:

  • Carrier doppler = Carrier lock loop (FLL, PLL)
  • Code doppler = Code locked loop (DLL)
  • Data = Code locked + Carrier locked
  • PVT = Data demodulation + Pseudorange

OUTCOME OF THE GUEST LECTURE

  • The students understood the industry perspective of IoT in Healthcare.
  • They also gained inputs on the used cases and case studies in the field of signal processing.
  • They learnt about GNSS receivers and tracking algorithms.
  • The Lecture helped to bridge the gap between the classroom and the real world environment.
