Abstract:
1. A wireless communication system for communicating transmission data comprising: a transmitter configured to generate and to transmit a signal including the transmitter configured to generate a scrambling initial value using at least a part of the physical layer header section, the transmitter configured to count a number of logics “1” and a number of logics “0” in said part of the physical layer header section, the transmitter configured to generate the scrambling initial value based on the number of logics “1” and the number of logics “0” in said part of the physical layer header section, the transmitter configured to scramble the data section using the scrambling initial value, the transmitter configured to transmit the physical layer header section using a first modulation method and a first encoding rate with a first signal to noise ratio, the transmitter configured to transmit the data section using a second modulation method and a second encoding rate with a second signal to noise ratio, the first signal to noise ratio being less than the second signal to noise ratio; and a receiver configured to receive a signal from the transmitter, the receiver generating a descrambling initial value using at least a part of the physical layer header section, the receiver descrambling the data section using the descrambling initial value.
