Dual header pulse interval modulation for digital communication systems

This thesis presents a digital communications system with the Dual Header Pulse Interval Modulation (DHPIM). In particular, a single user transceiver based on DHPIM is proposed. The system uses Pseudo Random Noise chips at a wide bandwidth spectrum. DHPIM is a pulse modulation that separates pulses by a number of time slots depending on the data to be transmitted. This scheme is more efficient than the Pulse Position Modulation in terms of transmission rate and bandwidth requirements. The average data rate of proposed system is 250 Mbps. The study was based on MATLAB simulations and knowledge of DHPIM and Direct Sequence Spread Spectrum (DSSS) systems. A DHPIM system for digital transmission is presented and its performance is evaluated.
