In this paper, we propose a low complex architectural design for adaptive decision feedback equalizer (ADFE). For this we recast the ADFE equations using distributed arithmetic (DA), which enables the implementation of ADFE without multipliers. The design is based on the distributed arithmetic based formulation of it. It is further shown that high order filters, which are required to implement high speed ADFEs can be realized using only look-up-tables (LUTs) and shift-accumulate operations. A novel approach was proposed to replace feed forward and feedback filters of ADFE with a single DA unit. By proper initialization, it is also shown that a low complexity ADFE architecture can be obtained.
