Abstract :
A new approach for the architecture of an all digital wideband modem is presented. The key feature of this approach is a lower processing rate than the Nyquist rate (the input sampling rate) and even the symbol rate. Due to the freedom in choosing the processing rate, the designer is able to arbitrarily select and use digital components, independent of the speed of the integrated circuit technology. This architecture is particularly suited for high data rates with applications to giga-bit/second satellite channels, multiple access, optical links and interactive cable-TV
