N2 - The paper presents an orthogonally-Anchored adaptive linear interference rejection technique in space-Time rake processing. With the use of a super short training sequence, the initial space-Time adaptive filtering vector composed of two mutually orthogonal components is calculated by using a projection-based filter optimization technique. The adaptive filter optimization based on the pre-optimized initial weight vector is implemented to efficiently suppress the multiuser access interference in the filtering procedure. In contrast to the blind space-Time rake processing, the computation efficiency exhibited in the suggested approach is achieved by implementing the linear optimization for the filtering vector in reduced-dimensional (or full-dimensional) space-Time complex vector spaces instead of using eigenvector-based processing, in which the optimization of the filtering vector in full-dimensional data vector space is required.
