A method for conducting a community wagering game on a plurality of gaming terminals includes conducting base wagering games on the plurality of gaming terminals and triggering a community event in which at least one randomly selected outcome is shared by all participating gaming terminals. The interference estimation is performed on average over each frame for each mobile station individually in both frequency and time domains. In particular, the present invention allows a consumer to search for, compare prices and order products from many different merchants located on the Internet. Each step is formed of a washable fabric cover stretched across a high-density foam core, the core being usually of regular block shape, but alternatively in the shape of a trapezoidal block, right wedge, or other.
