Design of complex coefficient variable fractional-delay allpass digital filters by eigenfilter approach
Jong-Jy Shyu,Soo-Chang Pei,Cheng-Han Chan +2 more
- 21 Jun 2010
TL;DR: In this article, the technique of eigen filter approach is applied to the design of complex coefficient variable fractional-delay (VFD) all-pass digital filters, and the objective error function is formulated into a quadratic form aTQa where a is a coefficient vector and Q is a real, symmetric and positive-definite matrix.

Ming-Yang Chen,Soo-Chang Pei,Hsuan-Jung Su +2 more
- 11 Sep 2005
TL;DR: A set of quasi-orthogonal space-time block codes for four transmit antennas that achieves full diversity and high coding gain whenever a square lattice constellation is adopted.

Two-band IIR quadrature mirror filter design
Sy-Been Jaw,Soo-Chang Pei +1 more
TL;DR: In this article, two types of two-band IIR quadrature mirror filter structure are propsed and the Remez exchange algorithm is used iteratively to optimise the filter response, which results in an equal-ripple design.
