Abstract: The conventional complex channel model for wireless indoor propagation is extended to include the frequency dependence of individual rays. Multiple ray paths are resolved using high-resolution digital signal processing algorithms. The Cramer - Rao bound is used as a benchmark where a newly developed modified eigen-matrix pencil method is proven to be most successful.
