摘要
The HFB structure is a suitable candidate to realize a wide-band AID convertor for the Software-Defined Radio (SDR) systems. Two MIMO Time-Division Multiplexing (TDM) and subband HFB architectures are compared with the classical one in this paper. Simulating in the time-domain, the MIMO HFBs exhibit a better performance than the classical one in terms of output resolution as well as the sensitivity to the realization errors of analysis filter bank. In opposite to the classical HFB case, the MIMO HFBs provide an LTI input-output relation. It is shown that the blind estimation and noise cancelation techniques may be used in the MIMO case for correcting the realization errors. The MIMO and classical HFBs are compared in terms of computational complexity as well.
