Advanced Modulation for Spectrally Efficient Communication

PI: Justin Coon

Department: Engineering Science

The proposed project relates to a new method of communicating digital information between two electronic devices, such as smart phones and base stations, laptop-to-laptop, etc. The method is known as discrete cosine transform orthogonal frequency-division multiplexing with index modulation (DCT-OFDM-IM). This method, which was recently invented in the Oxford Communications Research Group, has the potential for achieving spectral efficiency gains (the information rate that can be transmitted over a given bandwidth, measured in units of bits per second per Hertz) of more than 60% relative to state-of-the-art benchmarks currently used in 4G cellular communications, Wi-Fi, and digital video broadcast (DVB) systems. The overarching goal of this project is to develop a proof-of-concept demonstration of DCT-OFDM-IM in a practical setting using state-of-the-art development equipment.
