<p>A base station subsystem (102) includes at least one transmit branch (300) having a forward path (301) that includes a signal processing unit (330) coupled at an input to an input Fourier Transform Matrix (FTM) (320) and at an output to an output FTM (360). The transmit branch further includes two error compensation loops, an inner feedback loop that includes an inner loop feedback circuit (302) and an outer feedback loop that includes an outer loop feedback circuit (303). The inner feedback loop provides error compensation for error introduced by the signal processing section to a signal input to the transmit branch. The outer loop provides error compensation for all residual error introduced into the signal when routed through the transmit branch forward path after error compensation may be performed by the inner feedback loop.</p> |
