| 摘要 | A method and apparatus for data modulation in an antenna array include: storing input data comprising of a plurality of data bits, in a buffer; generating a pseudo random number; computing a transmission mode from the pseudo random number; based on the computed transmission mode and the number of antenna elements in the antenna array, computing a particular phase offset for each antenna element; sequentially providing the stored input data, one bit at a time, to each antenna element; and transmitting the input data from each antenna element according to the computed particular phase offset for said each antenna element. | ||
