Abstract:
Embodiments provide an area, cost, and power efficient multi-service transceiver architecture. The multi-service transceiver architecture simplifies receiver/transmitter front ends needed for a multi-service architecture, by replacing significant portions of multiple receiver and/or transmitter front ends with a single ADC and/or DAC, respectively. In embodiments, a plurality of received service contents are combined into one composite analog/RF signal and applied to an ADC. The ADC converts the composite signal into a composite multi-service digital signal. Digital techniques are then used to separate the plurality of service contents into a plurality of respective digital streams that each can be independently demodulated. Similarly, in the transmit direction, a plurality of digital streams, including a plurality of service contents, are combined into one composite digital signal. The composite digital signal is applied to a DAC to generate a composite multi-service analog/RF signal for subsequent transmission over a coaxial cable or wirelessly via an antenna.
