PROJECTS
Proscout Drive Testing Jan 2011 – May 2011
University of Maryland, College Park
• Drive test T-Mobile’s wireless network using Proscout, in and around the Washington DC area
• Measure the Received Signal Strength Levels (RSSL), Bit Error Rates (BER) and Carrier to Adjacent channel Interference (C/A) across the network.
• Measure signal strength of 3G data network using TEMS hardware for in-building coverage
LTE (Long Term Evolution) OFDM (Orthogonal Frequency Division Multiplexing) System Jan 2011 – May 2011
University of Maryland, College Park
• Design an LTE OFDM system using Matlab
• Design transmitter, channel and receiver for a given number of active subcarriers and channel bandwidth
• Implement variable modulation schemes based on channel conditions
• Incorporate pilot symbols as cell-specific reference signals
• Implement CP (Cyclic Prefix) as a Guard Interval and also to mitigate ISI (Inter Symbol Interference)
STK (Satellite Tool Kit) Project Sept 2010 – Dec 2010
University of Maryland, College Park
• Implement constellation of GEO stationary satellites with different mean anomalies
• Estimate using STK, the number of satellites required to provide a certain coverage area, using different central angles at the transmitter
• Estimate time a MEO satellite will cover a certain area, given a minimum elevation angle
• Compute access time of a satellite using Access Lists and Chain Access report
• Simulate LEO to GEO interference in a satellite communications system and use the link information report to observe the Carrier to Noise ratio in the link
WiSpy Project Sept 2010 – Dec 2010
University of Maryland, College Park
• Analyze the WLAN network within a certain area on campus using MetaGeek’s inSSIDer software and WiSpy DBx hardware
• Observe changes in signal strength due to injected interference by multiple sources using Wi-Spy in conjunction with Channelyzer Pro
