DATA TRANSMISSION METHOD FOR MITIGATING USER INTERFERENCE

摘要

A data transmission method for mitigating user interference is provided to remove residual ISI(Inter Symbol Interference) in single transmission or re-transmission and manually adjust channel selectivity to acquire a diversity gain. A data transmission method for mitigating user interference comprises the following steps of: transmitting initial data(S110); receiving a re-transmission request signal for the initial data; generating re-transmission data obtained by shifting a phase of the initial data on signal constellation according to the re-transmission request signal(S140); and transmitting the re-transmission data(S150). The re-transmission data is generated by bit-masking the initial data. The initial data is a scrambled code. The phase of the initial data is shifted at a bit level.
