A heterodyne receiver with the Hilbert transformer is in principle known to cope with signals in arbitrary frequency bands.
Moreover, the dual frequency conversion has been proposed to mitigate the interference due to the imperfection of actual Hilbert transformers.
This paper evaluates the performance of the receiver where the frequency response of the desired band differs from that of the image band.
Furthermore, we propose a moved scheme to improve the performance.
The proposed scheme consists of the estimation of the Hilbert transformer's imperfection and the baseband linear filtering.
Computer simulation shows that the proposed scheme achieves by 9dB better BER performance than the conventional scheme when CIR (Carrier-to-Interference Ratio) is -60dB and BER is $10^{-1}$. |
