摘要:
The invention of a method and an apparatus for reception of long transmission range Bluetooth signals impaired by multipath are disclosed. The new reception method and apparatus proposed allows to increase the transmission range for data transmission in Bluetooth. The invention proposes the use of a new FDE adapted to SC transmission without a GI or CP. The proposed FDE very successfully mitigates ISI while being very implementation-friendly.
摘要:
An automatic gain control and its method are disclosed. An average power computing unit computes the power of a received signal. A power range monitoring unit monitors its change. If the signal power fluctuates around a threshold, the system enters an acquisition mode and the gain is tuned back to a default value. If the signal power is above an upper limit of a tracking range, a gain decreasing unit reduces the gain. If the signal power goes below a lower limit of the tracking range, a gain increasing unit raises the gain. Once the power falls in the tracking range, the system enters a tracking mode to make immediate responses toward the gain of the received signal.

摘要:
A method for enhancing the Bluetooth transmission speed and robustness of an emitting end and a receiving end is provided. The method is utilized in a system having an emitting end and a receiving end, wherein at least one of the emitting and receiving ends is provided with BlueSPEED-PSK or BlueSPEED-DELTA-PSK (adapted Gray coded D16PSK) modulation with optional FEC.
