The increase of data collected every second requires a high data transfer system. Every day, 2.5 quintillion bytes of data are created [1]. This huge amount of data is col-lected from different devices and sensors. We proposed a new and novel scheme for a huge data transfer system. Our system introduces a new modulation and demodulations scheme for Ultra Wideband (UWB) communications systems. The main motivation for our scheme is to increase the amount of data collected from biosensors and medical data collections. This novel scheme is based on the Modified Hermite Pulses (MHP). The modulated signal is composed of a sum of different MHP where the orthogonal property of these signals provides an easy recovery scheme. Each signal of those MHP can be easily distinguished from the others. Our demodulation system is based on the fact that these signals are easily distinguishable. We first proposed an 8 bits system where each 2 bit can be represented by a sum of an MHP pulse. This will require 4 different MHPs pulses. Then, all those MHP are added together in one time slot in order to represent the transmitted signal. A maximum of 3 MHP pulses from each type is required to represent all the different combinations of the 2 bit signal. We achieved a 0 BER for this system where the signal to noise ratio (SNR) was 10 dB. We also introduced a time shifted Mod-ified Hermite Pulses (MHP) where the addition of 4 new shifted MHP increased the number of bits transmitted to 16 bit. However, for the same SNR of 10 dB, our BER was iv 0.1. We further tested the system that only used non shifted MHPs and it was found that the BER was less than 0.1 for a noise level similar to the signal amplitude.
