A direct digital synthesis (DDS) device includes a first digital to analog converter (DAC) and a second DAC, wherein the first and second DACs are configured to respectively process first and second samples of a digital amplitude signal. The DDS device also includes a switch configured to receive first and second DAC output signals from the first and second DACs, respectively, and selectively switch among at least the first DAC output signal and the second DAC output signal to generate a combined signal. The DDS device also includes a signal mixer configured to receive the combined signal and a mixer clock signal, wherein the signal mixer is a multi-mode mixer further configured to operate in (i) a pass-through mode where the combined signal is provided as a mixed signal, and (ii) a mixing mode where the combined signal is mixed with the mixer clock signal, to generate the mixed signal.

A method of scheduling at least one set of communication slots based on selected opportunities. The method comprises steps of providing a computer program product with a set of network devices of a transmission system, wherein each network device of the set of network devices of the transmission system comprises: a processor; and a computer readable medium that is accessible by the processor and stores the computer program product. When the product is executed by each processor of the transmission system, each processor is caused to: input a set of contention parameters into the computer program product, select whether the at least one set of communication slots relates to a set of transmission opportunities or a set of response opportunities, compute a number of communication slots that defines the at least one set of communication slots, schedule the at least one set of communication slots based on the selected opportunities.

A transmission system that includes an initiator, a responder, and a computer program product. The initiator includes a first processor and a first computer readable medium that is accessible by the first processor. The responder includes a second processor and a second computer readable medium accessible by the second processor, wherein the responder is operatively in communication with the initiator. The computer program product is stored on the first computer readable medium and on the second computer readable medium. When the computer program product is executed by the first processor of the initiator and the second processor of the responder, the computer program product establishes a contention free schedule between the initiator and the responder to communicate at predetermined time periods.

A method of establishing a contention resolution schedule in a transmission system. The method comprises steps of: providing a computer program product with a set of network devices of the transmission system, the transmission system comprises at least: an initiator having a first processor, and a responder having a second processor that is operatively in communication with the initiator; wherein when the computer program product is executed, the processors are caused to: instruct the initiator to output an initiation message including at least a set of initiator transmission opportunities and to output a contention parameter message, instruct the responder to accept a set of responder response opportunities and to output a set of responder transmission opportunities, instruct the initiator to select a set of initiator response opportunities and accept a set of initiator response opportunities, and establish the contention resolution schedule in the transmission system.
