A high-throughput pipelined architecture for blind adaptive equalizer with minimum latency

In this paper, we propose a pipelining architecture for the FIR portion of the multilevel modified constant modulus algorithm (MMCMA). We also provide the correction factor that mathematically converts the proposed pipelined adaptive equalizer into an equivalent non-pipelined conventional MMCMA based equalizer. The proposed pipeline method uses modules with 6 filter coefficients, resulting in an overall latency of a single sampling period along the main transmission line. The basic concepts of the proposed architecture is to implement the FIR filter and the algorithm portion of the equalizer such that the critical path has one complex multiplier and two adders.
