We formulate the equalization problem following a Bussgang approach, derive the coherent MMSE input synbol estimator, and assess the performances of the analyzed semi-blind Bussgang equalizer in typical sparse channels. The simulations show that the semi-blind linear equalization algorithm allows flexible integration of the training in the eqaulization procedure while the sparse, not connected, support favourably copes with channels characterized by long delayed echoes.","PeriodicalId":88900,"journal":{"name":"International Conference on Digital Signal Processing proceedings : DSP.

Multimedia algorithms in their majority consist of regular repetitive loop constructs. In this paper, a novel control architecture for implementing such loop intensive algorithms is described. The proposed control unit takes advantage of the regularity of computations in order to serve as high performance parametric controller of multimedia datapaths. The control unit cooperates with datapath modules and their corresponding controlling FSM. Algorithmic flow dependencies which determine the appropriate loop sequencing are mapped on a LUT. For another algorithm to execute, LUT context and FSM configurations only have to be reprogrammed. Thus, partial reconfiguration possibilities for implementing multimedia algorithms on programmable platforms can be exploited. For demonstration purposes, a matrix multiply algorithm implementation case is investigated. Compared to a software realization on ARM7 processor, significant performance improvements are reported.","PeriodicalId":88900,"journal":{"name":"International Conference on Digital Signal Processing proceedings : DSP.
