FRAME/SLOT SYNCHRONIZATION FOR U.S. DIGITAL CELLULAR TDMA RADIO TELEPHONE SYSTEM |
摘要 |
Frame/slot synchronization is applied to a received Time Division Multiple Access (TDMA) signal and a temporal position of a reference feature is acquired, such as a synchronizing bit stream or preamble, associated with a desired time slot. The desired time slot is but one of a plurality of time slots that comprise a frame. Verification that the acquired temporal position corresponds to the desired time slot is performed by repetitively estimating a temporal position of the reference feature in a subsequent frame and sampling the subsequent frame at the estimated temporal position to determine if the reference feature is present. The temporal position of the reference feature of the desired time slot relative to the frame is maintained over a plurality of received frames.
