This work illustrates how the Hilbert transformer design method and the word length used can influence the Bit Error Ratio (BER) performance of multicarrier systems. The implementation of new digital even order allpass based Hilbert transformers is proposed. The Hilbert transformer realization is developed using worst case phase sensitivity minimization of each individual first order allpass sections. This design procedure improves the accuracy of the Hilbert transformer phase deviation even for severe word length limitations and fixed point arithmetic applications. The operation of a multicarrier system is simulated and the experimental results demonstrate that a good BER performance can be achieved using 2-bit even order allpass based Hilbert transformers. |
