Cascading baseband processors

摘要

Cellular processors are cascaded to provide different configurations, which result in higher-capacity base stations, increased numbers of simultaneous users over one frequency band, and/or aggregation of several carriers while still using only one radiofrequency (RF) chipset. The processors are aligned in both time and frequency, with each processor having a data port that allows data exchange with the other processors. The data alignment and exchange allow the processors, in the aggregate, to act as a single unit, resulting in a scalable architecture that can accommodate different system configurations.

1. A system, comprising:
a first slave processor, comprising:
a first configurable delay configured to synchronize a first slave processor clock to a master processor clock of a master processor, the first slave processor clock being synchronized responsive to a master clock signal and a synchronization signal received by the first slave processor from the master processor;a first radiofrequency receiver configured to receive radio frequency data from the master processor to generate combined radio frequency data utilizing at least radio frequency data of the first slave processor and the radio frequency data from the master processor; anda first radio frequency transmitter configured to transmit the combined radio frequency data.
