Definitions
- the invention relates to new tram sequences with optimized cross-correlation for use in cellular mobile radio.
- the object of the invention is now to develop sequences with equally favorable autocorrelation properties but improved cross-correlation properties. This is achieved by two special sequences, which form the binary representation
- GSM Global System for Mobile Communications
- FIG. 1 shows the auto and cross correlation properties of the known GSM train sequences
- FIG. 2 shows these properties of the training sequences according to the invention.
- x sh ⁇ f t is shown in multiples of the image duration (T).
