Pseudo random noise based spread spectrum modulation scheme for secure UWB wireless communication /
A Pseudo Random Noise Generator (PRNG) using 24 bits Linear Feedback Shift Registers (LFSR) have been proposed to generate a sufficiently long period of key sequence for a secure UWB communication application. The Direct Sequence Spread Spectrum (DSSS) principle is employed in the system as a data m...

| 520 | |a A Pseudo Random Noise Generator (PRNG) using 24 bits Linear Feedback Shift Registers (LFSR) have been proposed to generate a sufficiently long period of key sequence for a secure UWB communication application. The Direct Sequence Spread Spectrum (DSSS) principle is employed in the system as a data modulation and transmission technique due to its low Power Spectral Density (PSD).The investigation is carried out to analyze the performance of UWB pulse generator by using Avalanche transistor which able to generate nanosecond pulses that contained data embedded with the key to be transmitted. The designed UWB transmitter circuit has been simulated using NI Multisim 11.0. The circuit successfully generated a kind of inverted Gaussian pulses with the best pulse width achieved is 1.91 ns and pulse amplitude is 5.72V. The Power Spectral Density (PSD) of the pulses satisfies the specification of FCC mask defined with the magnitude of -81.5 dBm at 3.1GHz frequency. In fact, the PRNG pass the NIST Test Suite randomness tests. With the features such as simple structure, high speed and low power as low cost this circuit system is applicable to UWB wireless communication system. | ||
