This paper proposes hardware architectures of adaptive equalizers applicable to both the quadrature amplitude modulation (QAM) and vestigial sideband modulation (VSB) systems. This paper presents digitization methods for QAM and VSB systems requiring a low hardware cost with the performance comparable to that of the algorithm employing floating-point operations. To reduce the hardware cost of the high definition television (HDTV) equalizers, we also propose a pipelined architecture that processes some parallel parts sequentially.
