There is provided a transposed Farrow structure for a receiver for a Software Defined Radio (SDR) system, a feedforward synchronizer for an SDR receiver comprising such a transposed Farrow structure and a method for processing a received signal in an SDR receiver. The transposed Farrow structure is arranged to implement: a) sample rate conversion (SRC) for converting a received signal r having a sampling rate of 1/T.sub.1 to a transmitted signal y having a sampling rate of 1/T.sub.2 b) timing adjustment using an estimated timing error .tau.; and c) matched filtering of the received signal. The feedforward synchronizer includes the transposed Farrow structure and a feedforward estimator for generating an estimated timing error .tau.. The method includes the steps of performing, in the transposed Farrow structure, sample rate conversion (SRC) for converting received signal r having a sampling rate of 1/T.sub.1 to a transmitted signal y having a sampling rate of 1/T.sub.2; performing, in the transposed Farrow structure, timing adjustment using an estimated timing error .tau.; and performing, in the transposed Farrow structure, matched filtering of the received signal.
