HIGH BIT RATE INFRARED COMMUNICATION SYSTEM FOR OVERCOMING MULTIPATH. |
摘要 |
A wireless infrared (IR) communications system (100) for communicating packetized information (302) between a Control Module (12) and a plurality of User Modules (14) via infrared transceivers (300/320) and having a selectable communications path. In this system at least the User Modules (14) have a plurality of IR device arrays (A1-A6) for receiving IR signals (312/312') in relatively narrow IR field of view sectors, and a selector (20), coupled to said plurality in IR device arrays (A1-A6), for selecting a communication path between the Control Module (12) and one of said plurality of IR device arrays (A1-A6), based at least partly on received signal (302') integrity, so as to overcome reception errors caused by multipath interference. |
