Abstract

A dynamically reconfigurable universal transmitter system is disclosed herein. The electronic device includes multiple transmitter resources for generating transmission signals, an output bus, and an antenna summer coupled to the output bus. The output bus is selectively coupled to the plurality of transmitter resources and it selectively receives transmission signals from the plurality of transmission resources. The antenna summer stores transmission signals received on the output bus.

Claims

1. A configurable transmitter resource for generating any one of a plurality of channel formats, the configurable transmitter resource comprising:

a memory comprising information for the plurality of channel formats to which the configurable transmitter resource can be configured;

a processor coupled to the memory, the memory comprising instructions and data that, when executed on the processor, implement a method for operating the configurable transmitter resource; and

a universal transmitter unit coupled to the processor and comprising a plurality of virtual resources operating within a system cycle, wherein each of the virtual resources is configured to selectively provide one of a plurality of data samples for modulating a data signal,

wherein the plurality of virtual resources are respective time-sliced uses of a same hardware resource.

2. The configurable transmitter resource recited in claim 1, wherein the virtual resources are configurable to modulate data for a plurality of modulations schemes.

3. The configurable transmitter resource recited in claim 1, wherein the plurality of channel format information is stored in a slot format table including any combination of puncturing information, slot size, spreading factor, or identification of a source of data.

4. The configurable transmitter resource recited in claim 1, further comprising:

at least one parameterizeable interface coupled to the local memory, the parameterizeable interface configurable to any one of the plurality of transmission signal types designated by control information.

5. The configurable transmitter resource recited in claim 1, further comprising a plurality of universal transmitter units configured to be initiated in series and operated in parallel using a time-sliced process.

6. The configurable transmitter resource recited in claim 5, wherein a clock speed of the universal transmitter units is relative to a system cycle and the number of virtual resources.

7. The configurable transmitter resource recited in claim 1, wherein each of the virtual resources comprises a setup portion, a process portion, and a save portion.

8. The configurable transmitter resource recited in claim 7, wherein the virtual resources are configured such that the setup portion of one of the virtual resources operates in parallel with the processing portion of another of the virtual resources.

9. The configurable transmitter resource recited in claim 1, wherein the memory further comprises:

a primary table configured to provide an antenna sequence to which the universal transmitter unit is dedicated for a particular time slice or time slot within a system cycle; and

a secondary table configured to provide operating information to the universal transmitter unit to enable the universal transmitter unit to process data for an antenna designated by the primary table,

wherein the primary table and the secondary table are executable by the processor.

10. In a configurable transmitter resource having a universal transmitter unit and a memory including a plurality of channel formats to which the configurable transmitter resource can be configured, a method comprising:

selectively providing, by at least one of a plurality of virtual resources operating within a system cycle and located in the universal transmitter unit, one of a plurality of data samples for modulating a data signal in accordance with any one of the plurality of channel formats;

modulating, by the at least one of the plurality of virtual resources, the data signal in accordance with the channel format; and

outputting the modulated data signal,

wherein the plurality of virtual resources are respective time-sliced uses of a same hardware resource.

11. The method recited in claim 10,

wherein the configurable transmitter resource has a plurality of universal transmitter units,

the method further comprising configuring the plurality of universal transmitter units to be initiated in series and operated in parallel in a time-sliced manner.

12. The method recited in claim 10, further comprising:

providing, from a primary table located in the memory, an antenna sequence to which the universal transmitter unit is dedicated for a particular time slice or time slot within a system cycle; and

providing, from a secondary table located in the memory, operating information to the universal transmitter unit to enable the universal transmitter unit to process data for an antenna designated by the primary table.

13. The method recited in claim 10,

wherein each of the virtual resources comprises a setup stage, a process stage, and a save stage,

the method further comprising operating the setup stage of one of the virtual resources in parallel with the processing stage of another of the virtual resources.
