Abstract:
1. A modulating device for modulating and demodulating data for transmission from a first device to a second device, comprising modulating means capable of modulating and demodulating the data according to at least a first and a second modulation technique using common digital modulation components, a switching means for automatically switching between at least the first and the second modulation techniques, and a plurality of building blocks, wherein at least one of the plurality of building blocks is used for at least one of modulating and demodulating data according to the at least first and second modulation techniques, wherein at least one building block comprises a programmable finite impulse response filter, a look-up table, and a serial-to-parallel converter, and wherein the programmable finite impulse response filter is used as a correlator in a first mode of the first modulation technique.
