Multiple Devices Communicating on a Single Communication Channel with a Consecutively Sequenced Signal
First Claim
1. An transmitting device comprising:
- a transmitting circuit configured to send a consecutively sequenced signal sequentially containing a plurality of messages to a receiving device; and
a duty cycle adjustment circuit configured to determine a determined duration between one of the plurality of messages and an adjacent message and to instruct the transmitting circuit to send said one message based on the determined duration, wherein the consecutively sequenced signal is characterized by an essentially randomized duty cycle.

Abstract
The present invention provides apparatuses, methods, and computer readable media for supporting communications for a plurality of transmitter-receiver pairs on a common frequency spectrum. A transmitting device transmits a consecutively sequenced signal sequentially containing messages to a corresponding receiving device. A duty cycle adjustment circuit determines the duration between adjacent messages so that the consecutively sequenced signal is characterized by a randomized duty cycle. The duty cycle adjustment circuit selects the duration from a sequence that is characterized by an average duration. The duty cycle adjustment circuit obtains the duration from an array by determining an index from a function of a random variable. A receiving device receives a consecutively sequenced signal sequentially containing messages from a transmitting device, where the consecutively sequenced signal is characterized by a randomized duty cycle. A processing circuit detects the messages and initiates an error signal when a predetermined number of consecutive invalid messages are detected.
