Tdma speed
WebWe present the Jam-TDMA (J-TDMA) protocol, which eliminates the need for having a bus master through the use of a nondestructive jamming signal for frame synchronization. We give a detailed description of the J-TDMA protocol and show how to minimize the effects of speed differences among nodes on TDMA systems, which can be critical for low-cost ... WebA new algorithm is presented for estimating mobile speed for handoff in hierarchical cellular systems. The proposed algorithm is based on normalized autocorrelation values of received signals to estimate mobile speed; it contains six steps. First, the instantaneous power of the received baseband signal is calculated to remove the frequency offset and …
