Thesis Defense on DFT Computation over Mixed Lattices

Group member Diego F G Coelho defended his thesis on signal processing and fast algorithm design.

Diego F G Coelho has defended a thesis entitled

"Discrete Fourier Transform Computation Based on an Algebraic Integer Representation" [Transformada Discreta de Fourier Baseada em uma Representação para Números Complexos com Inteiros Algébricos]

to the Graduate Program in Statistics. The work was advised by Dr R J Cintra. Examining committee was composed by Dr H M de Oliveira, Dr F M Bayer, and Dr A D C Nascimento.

Congratulations to Diego!
