Abstract:
Short training field (STF) for use within single user, multiple user, multiple access, and/or MIMO wireless communications. An STF design as is made such that the power associated with the tone indices at the edges of the STF design is relatively less than the power associated with the tone indices more centrally located within the STF design. Also, when multiple respective operational modes are supported (e.g., 1 MHz and 2 MHz), the respective STF designs corresponding to those respective operational modes have a great deal of similarity. For example, the respective STF designs for different respective operational modes may have certain common STF tone indices among those respective STF designs.
