Image Number 3 for United States Patent #7693040.
A baseband processor includes a processing switch for performing orthogonal frequency division multiplexing operations on data packets and routing the data packets in the baseband processor. Additionally, the baseband processor includes digital signal processors for performing symbol processing operations on the data packets. The baseband processor is scalable such that digital signal processors may be added to, or removed from, the baseband processor. Further, the baseband processor is programmable such that the symbol processing operations may be distributed among the digital signal processors.
