Modular architectures for adaptive multichannel lattice algorithms

A modular architecture for adaptive multi-channel lattice algorithms is presented. This architecture requires no matrix computations and has a regular structure which significantly simplifies its implementation in comparison with the multichannel (matrix) version of the same algorithms. Because the suggested architecture exhibits a high degree of parallelism and local communication, it is well suited for parallel hardware (VLSI) implementation. The derivation of this modular architecture demonstrates a powerful principle which may become a basic tool for analysis and design of structured processing architectures such as systolic arrays and wavefront array processors.
