DISTRIBUTED ANTENNA SYSTEM USING SIGNAL PRECURSORS

摘要

A system and method for distributing multiple wireless carriers to transmission sites is disclosed. Carrier precursors are distributed which are digital in format and compressed in bandwidth. The individual carrier precursors are combined using time division multiplexing to eliminate the need for excess bandwidth allotments. A separate time division multiplexed control channel is created to communicate carrier configuration and operating status information. With the carrier precursor data and configuration information, a software-defined radio is used to create actual carriers at or near the transmission location. Creating carriers at or near the transmission location provides the additional benefit of reducing transmission losses between the transmit antenna and the signal generating radio.
