Finite-Precision Optimization of Time-Domain Digital Back Propagation by Inter-Symbol Interference Minimization
Paper in proceeding, 2017
We consider the effects of limited-resolution arithmetic on the performance of Time-Domain Digital Back Propagation. By minimizing resulting ISI of the quantized FIR impulse responses, we can achieve floating-point performance using 9-bit pairwise optimized filter coefficients.
