Abstract
Starting with some well known formulas of discrete sigma-pi orthogonality of bipolar vectors we introduce a quite general and easy strategy to obtain periodic interpolation schemes on dyadic grids including fast algorithms for explicit calculation. As special cases of our presented approach we mention dyadic trigonometric and Walsh-type interpolation.
