Energy Efficient Applications of RIS (Postdoctoral Research)
Supervisor name: Prof. Sonia Aissa
• Performance analysis of RIS with advanced spatial modulation schemes and ambient backscattering.
• Investigating realistic channel models for RIS
• Performance analysis of full-duplex two-way RIS
• Cooperative RIS framework analysis
Advanced Spatial Modulation Schemes: Performance Analysis and Applications (PhD thesis)
Supervisor name: Prof. Rakhesh Singh Kshetrimayum
• The need of the future generation of wireless communications is higher data rates at low cost with good quality of service (QoS).
• MIMO techniques have issues of multiple RF/optical chains with escalated system cost and power consumption.
• Spatial Modulation can resolve the drawbacks of MIMO. However to achieve more spectral efficiency, advanced spatial modulation techniques need to be explored.
• Performance analysis of advanced spatial modulation schemes are being explored for RF, body area network, optical free-space, underwater optical communication and hybrid FSO/RF systems. The channel models vary according to the applications.
•Analysis is done in terms of average symbol error probability (ASEP), outage probability or bit error rate (BER). Cost and power consumption analysis is also carried out.
Efficient broadcasting over a single frequency network (MTech Project)
Supervisor name: Prof. Neetesh Purohit
• Long Term Evolution (LTE) holds the promise to enhance the capacity and speed of mobile communication by supporting Multimedia Broadcast/Multicast Services (MBMS) over a single frequency network (MBSFN), where numerous cells transmit an identical waveform that is synchronized in time for a specific time interval.
• For improving the performance of SFN, ultra-extended cyclic prefix duration has been considered in this thesis to account for the larger delay spread especially in rural and hilly areas. The performance of the network for both extended and ultra-extended CP has been compared in terms of an important parameter called the spectral efficiency.
• The suitable cell radius for optimum performance has also been investigated and the achieved simulated results justifies the need to opt for ultra-extended CP at the cost of reduced OFDM symbols per slot.
Design of Radio Frequency Transmitter (BTech Project)
Supervisor name: Prof. Asima Adak
• Designed a four stage FM (frequency modulation) radio transmitter on a PCB (printed circuit board).
• Provided proper shielding to avoid noise, moisture in the absence of which the frequency of the tuned oscillator is pruned to change.
