METHOD FOR SELECTING PACKETS ACCORDING TO CHANNEL ENVIRONMENT IN LOCAL AREA WIRELESS PAN SYSTEM |
摘要 |
PURPOSE: A method for selecting packets according to a channel environment in a local area wireless PAN system is provided to satisfy a required peak throughput and a packet error rate by selecting packets corresponding to a channel state without lowering data transmission rate and spectrum efficiency. CONSTITUTION: One packet is exchanged between a master slot and a salve slot. The packet of a Bluetooth system is formed of an access code, a packet header, and a payload. A bit error rate is measured by the access code of the transmitted packet. A state of the channel is predicted by the measured bit error rate. The packet is selected by considering throughput and transmission delay of the Bluetooth system according to the predicted state of the channel. |
