Academic Projects

1. Wireless Modem Simulation: System-Level Design for a Mobile Wireless

User Terminal

Designed a simulation reference system for general packet data channel,

subject to Rician flat fading using MATLAB and designed a demodulator for

such a fading channel with QPSK modulation.

2. Internet Protocol (IP) Router Emulation

Developed a simplistic uni-directional router emulator application that

receives simulated IP packets in the data component of a UDP datagram,

analyzes the packets, makes a routing decisions based on a static routing

table and static firewall parameters and reports information about the

actions taken.
