1. A system for providing re-transmission of selected components of a signal, said system comprising:
- means for accepting said selected components of said signal to the exclusion of other components of said signal;
means for manipulating said accepted signal components wherein said manipulated signal components include a selected attribute corresponding to an attribute of ones of said excluded other components;
means for controlling said accepting means wherein said accepting means operates to terminate acceptance of said signal components at least in part as a function of said selected attribute; and
means for transmitting said manipulated signal components.

Abstract
A system and method for providing a re-transmitted signal substantially free of feedback is disclosed. According to a preferred embodiment of the present invention, a delay is utilized with select burst periods of a TDMA signal so as to re-transmit these burst periods coincident with a subsequent burst period of the original signal. Accordingly, the re-transmitted signal of the present invention is decoupled from the input of the original signal.

37. A system for use in a communication network having a first communication site and a second communication site, wherein re-transmission of selected TDMA periods of a first signal associated with said first communication site is provided, said system comprising:
-
a receiver accepting said selected TDMA periods of said first signal and excluding other TDMA periods of said first signal; a device adjusting said accepted TDMA periods to correspond with a TDMA period of ones of said excluded other TDMA periods; a transmitter operable to transmit said adjusted TDMA periods coincident with ones of said excluded other TDMA periods; and a controller operable with communication information from said first communication site and said second communication site selecting ones of said TDMA periods to associate with particular information to avoid interference with said transmitted adjusted TDMA periods. - View Dependent Claims (38, 39, 40, 41, 42, 43)

53. A signal repeater apparatus providing re-transmission of selected portions of an input signal, wherein said input signal is substantially free of feedback associated with the re-transmitted signal, said apparatus comprising:
-
a switchable input operable to admit said selected portions of said input signal; a signal delay device operable to introduce a predetermined delay with respect to said admitted portions of said input signal; and a controller operable to switch said switchable input to selectively refuse portions of said input signal not selected, wherein occurrence of said refused portions of said input signal corresponds to said predetermined delay. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 61, 62)

63. A cellular telecommunication signal repeater apparatus providing re-transmission of selected bursts of a TDMA input signal, wherein said input signal is substantially free of feedback associated with the re-transmitted signal, said apparatus comprising:
-
a switchable input operable to admit said selected bursts of said input signal; a signal delay device operable to introduce a predetermined delay with respect to said admitted bursts of said input signal, said predetermined delay substantially corresponding to a duration of the bursts of said TDMA input signal; and a controller operable to switch said switchable input to selectively deny bursts of said input signal not selected, wherein occurrence of said denied bursts of said input signal substantially correspond to said predetermined delay, and wherein said controller operates to deny portions of said input signal during re-transmission of said admitted signal portions.
