Abstract
A multi building block architecture may be configured to generate a waveform (a “target wideband signal”) for use in a wireless communication system, where the waveform supports a variety of baseband signals. The task of generating a target wideband signal can be divided into several tasks, each task relating to the generating of one of a plurality of sub-carrier bands. Each of the sub-carrier bands (sub-bands) may be generated by one of the sub-band building units included in the sub-band building blocks of the architecture. Several sub-bands may be formed, by a sub-band group building block, into a sub-band group. Multiple sub-band groups may be formed, by a wideband building block, into the target wideband signal.

A wireless communication device having a processing device, the processing device being configured to generate a target waveform by implementing a configurable multiple building block architecture comprising:
- a plurality of sub-band building blocks, each of the plurality of sub-band building blocks adapted to form a sub-band group signal such that a plurality of sub-band group signals are formed;
- and
- each of the plurality of sub-band building blocks further adapted to:
- receive one or more frequency domain signals to be combined into the target waveform;
- employ one or more sub-band building units, each sub-band building unit being independently configurable to build a respective sub-band with independent parameters by:
- receiving a given frequency domain signal among the one or more frequency domain signals;
- transforming the given frequency domain signal to a time domain signal;
- and
- filtering the time domain signal;
- each sub-band building unit being independently configurable to use independent parameters that are selectable to differ between at least two sub-bands;
- employ a sub-band group building block to form the sub-band group signal comprising one or more sub-bands outputted by the one or more sub-band building units;
