Equalizers which compensate the transmission characteristics of the transmission channels are important for ensuring the quality of data transmission and are inevitable especially in the data transmission using telephone networks. This paper describes a method of applying the parallel architecture (PA) which we have already proposed to an adaptive equalizer which utilizes the recursvie least square (RLS) method. The RLS method which is used to estimate and update the parameters of equalizers, is attractive as an effective algorithm because of its fast conversion. However, the complexity of its computation makes this method less popular than the least mean square (LMS) method, especially for adaptive equalizers which require the fast update of the parameters. Utilizing the parallel architecture with the method described herein it is able to execute the RLS method with the same amount of calculation time as that of the LMS method. The parallel architecture is expected to be applicable in practice because it has an architecture of regular structures and localized interconnections which are suitable for implementation in VLSIs.
