METHOD AND APPARATUS FOR PRODUCING A DETERMINISTIC SEQUENCE FROM AN IIR FILTER

Document Type and Number:

WIPO Patent Application WO1998012810

Kind Code:

A3

Abstract:

A method and apparatus for improved interference rejection, where the rejection is being accomplished by an IIR filter at the transmitter with complementary characteristics to an FIR filter of the receiver, such as a Tomlinson-Harashima transmit-precoder. The improvement is accomplished by providing the ability to preset the transmit and receive filters to the same state, thereby allowing for subsequent receptions to be deterministic. This method and apparatus is particularly useful for correcting for time-varying interference through the use of repeatable, deterministic, training sequences.
