Signal Design

Pseudorandom signals with low correlation are essential for low interference among users or channels sharing the common communication channel. In wireless communication systems, pseudorandom signals are used for

• Spreading and channelization

• Data scrambling

• User/cell identification

• Spectrum shaping

• etc.

Moreover, pseudorandom signals can be used to provide randomness and security for stream ciphers in cryptographic systems.

Our research interests include

• Theoretical design and analysis of pseudorandom sequences with desired properties in transform domain

• Theoretical design and analysis of binary and polyphase sequence families with low correlation

• Theoretical analysis of binary sequences with optimal autocorrelation

• Application of pseudorandom sequences with low correlation in communications, signal processing, and cryptography
