Analog communication systems: amplitude and angle modulation and demodulation systems, spectral analysis of these operations, signal-to-noise ratio (SNR) calculations for amplitude modulation (AM) and frequency modulation (FM) for low noise conditions.Digital communication systems: pulse code modulation (PCM), differential pulse code modulation (DPCM), digital modulation schemes: amplitude, phase and frequency shift keying schemes (ASK, PSK, FSK), matched filter receivers, bandwidth consideration and probability of error calculations for these schemes. Basics of TDMA, FDMA and CDMA and GSM.                                                              

Interview

• Shortlisted candidates (after the written test) will be interviewed on the same day.
• Apart from general problem solving questions, interview MAY also involve writing small code in C, Verilog/VHDL or microcontroller programming.
• A final shortlist, based on (i) the performance in the tests, (ii) the interview, (iii) the background and (iv) references will be the final list of admitted candidates.
• The admission decisions (i.e. screening, shortlisting, and others) will be made by the IIIT-D PhD Admission Committee, which will be final.

Travel logistics: For the outstation candidates (non-NCR) who are shortlisted to appear for the written test, IIIT-Delhi will reimburse their travel fare by second sleeper or public bus fare by the shortest route, which ever is cheapest. They will have to furnish the proof of travel. If a candidate decides to choose a different mode (e.g. 3AC, air, etc.), IIIT-Delhi will only reimburse the second sleeper or public transport bus fare by the shortest route.

Accommodation logistics: IIIT-Delhi will be able to provide accommodation to a limited number of candidates on a first-come-first-serve basis. Please indicate your preference in the entrance test confirmation form.

For other question, please refer to the Frequently Asked Questions.

More details on the tests and interviews will be posted on this page - so please check this page regularly for announcements.
