Apparatus and method for improving noise tolerance of TDMA links
First Claim
1. A method for reducing a required signal-to-noise ratio in a time division multiple access (TDMA) link of a mobile network, the network including a first node and a second node, the method comprising:
- receiving at the first node an initial TDMA signal burst from the second node;
determining link state variables, thereby synchronizing the first node to the initial TDMA signal burst; and
tracking the link state variables between the initial TDMA signal burst and subsequent receptions of TDMA signal bursts from the second node at the first node.

Abstract
A method for reducing a signal-to-noise ratio requirement in a time division multiple access (TDMA) link of a mobile network. The network includes a first node and a second node. The method includes receiving at the first node, an initial TDMA signal burst transmitted from the second node, and determining link state variables, thereby synchronizing the first node to the TDMA signal burst. The method further includes tracking the link state variables between the initial TDMA signal burst and subsequent receptions of TDMA signal bursts from the second node at the first node.
