In this paper, alow-complexity approach to implement a class of flexible frequency-band reallocation (FFBR) multi-input multi-output (MIMO) networks, which use variable oversampled complex-modulated filter banks, is introduced. Two alternatives in processing real signals using real input/output and complex input/output FFBR networks (or simply, real and complex FFBR networks, respectively) are considered. It is shown that to process each sample, the real case requires less number of real operations compared to its complex counterpart. Furthermore, the real case has a smaller growth rate in the number of real operations with respect to the prototype filter order. In addition, the real FFBR network eliminates the need for two Hilbert transformers whereas in the complex FFBR case, to achieve high efficiency in FBR, there is a need for high-order Hilbert transformers.
