Abstract :
The authors develop a hyperstable adaptive algorithm that can be used in the multichannel IIR (infinite impulse response) configuration and permits the high-order IIR or zero-pole configuration to be realized in the parallel form for joint process estimation. The multichannel IIR configuration cannot be implemented by using the conventional hyperstable algorithm. The high-order configuration implemented by the proposed algorithm has much better rounding-error performance than that implemented by the direct-form configuration. Simulations results are presented for both the parallel zero-pole and multichannel configurations
