According to one embodiment, the system of the present invention comprises a first and second media access control (MAC) interfaces to facilitate receipt and transmission of packets over an associated set of physical interfaces. The system also contemplates a first and second field programmable gate arrays (FPGA) coupled to the MAC interfaces and an associated first and second memory structures, the first and second FPGAs are configured to perform initial processing of packets received from the first and second MAC interfaces and to schedule the transmission of packets to the first and second MAC interface for transmission to one or more destination devices. The first and second FPGAs are further operative to dispatch and retrieve packets to and from the first and second memory structures. A third FPGA, coupled to the first and second memory structures and a backplane, is operative to retrieve and dispatch packets to and from the first and second memory structures, compute appropriate destinations for packets and organize packets for transmission. The third FPGA is further operative to receive and dispatch packets to and from the backplane.

    Abstract: A communications system improves performance of detecting a signal having an indication of a request to change communications states by making at least two positive identifications of the request in a given time frame. The system may further improve performance by applying a difference in power levels for a non-request state (i.e., steady state or ‘control hold’ state) versus a request state (i.e., ‘request to change’ state). In one particular application, a base station determines a request to change communications states with a reasonably high probability of detection and a reasonably low probability of false detection. The system has a reduced number of erroneous communications states, such as erroneous traffic channel allocations. The detection technique is compatible with 1xEV-DV systems and I-CDMA systems, but general enough to support systems employing various other communications protocols used in wired and wireless communications systems.

    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.
