“…This synchronization function can be easily implemented through polyphase filter banks [5]. The figure 2 summarizes briefly such architectures, where the symbol timing recovery can be achieved either in a feedforward or a feedback mode.…”

“…only. But in this case, a feedforward symbol timing recovery needs at least a second matched filter, making the overall scheme unnecessarily expensive, as shown in [5], where the interpolator is simply incorporated in the MF. This compact approach allows the Interpolating Matched Filter (IMF) to output only one s.P.s., which is applied in the sequel.…”

sampling clocksAbstract. This contribution deals with full digital modem architectures, and more specifically with multirate demodulators. We aim at an overall complexity minimization of the receiver structure, by implementing a completely asynchronous sampling scheme, in conjunction with a single optimized filtering module, which carries out the inter-symbol interference cancellation along with a specific interpolation algorithm. This allows to decrease the oversampling ratio down to the theoretical bound, thereby restraining computational requirements, while reducing dramatically the traditional analog circuitry. Concretely, such a multirate demodulator should ultimately appear as a low-cost AID converter operating at a unique sampling frequency, followed by an ASIC. A
