Abstract
A method and apparatus for generating training sequence codes in a communication system. In the method, a pair of sequences A and B having cross-correlation properties as well as autocorrelation properties are generated, and protection sequences A′ and B′ are generated by copying last L symbols of the sequences A and B, respectively. The training sequence codes are generated by locating the protection sequences A′ and B′ in the most significant positions (MSPs) of the sequences A and B. The training sequence codes can be extended and applied to 16-QAM and 32-QAM used in a GERAN system, and the use of such training sequence codes enables data to be efficiently transmitted/received without performance deterioration in a GERAN system.
