Abstract :
Some real-time DSP experiments with adaptive IIR filters are addressed in this paper. The performance comparisons involve the LMSEE, the BRLE and the QCEE algorithms, A discussion of the main characteristics of each algorithm is included. Some aspects of the implementation involving the updating algorithm, the normalization, the quantization strategy and the internal scaling are discussed. Preliminary results show that finite wordlength effects are more disturbing in the BRLE algorithm than in the QCEE algorithm
