Patent ID: 8135082

Claim:
A method for performing burst mapping on transmission data by a transmitter in a mobile communication system using a 16-ary Quadrature Amplitude Modulation (16-QAM) scheme, the method comprising: generating control information bits and user data bits by encoding input control information and user data; dividing the control information bits and user data bits into more than two bursts; arranging a Training Sequence Code (TSC) in a center of each burst, placing the encoded control information bits according to reliability characteristics of modulation symbols based on the 16-QAM scheme in positions adjacent to the TSC, and placing the encoded user data bits according to the reliability characteristics of the modulation symbols based on the 16-QAM scheme in a start position and an end position of each burst; selecting control information bits to be swapped from among the control information bits; if positions where the selected control information bits are located are higher-reliability positions, swapping the selected control information bits with user data bits in corresponding higher-reliability positions among the user data bits and adjacent positions to the selected control information bits; and if the positions where the selected control information bits are located are lower-reliability positions, swapping the selected control information bits with user data bits in corresponding lower-reliability positions among the user data bits and adjacent positions to the selected control information bits.
