This paper provides a new approach to the multichannel linear prediction problem. To solve the consequently re defined problem in an order-recursive manner, a new mul tichannel Levinson algorithm is presented by virtue of the time-varying Wiener filter theory . The new algorithm is computationally efficient relative to the Levinson- Wiggins Robinson algorithm and its variants since it avoids any ma trix operations and needs scalar operations only. Further more, the new algorithm is optimum in that it produces the exact minimum prediction error power.
