A system comprises a transmitter configured to receive at least one message that corresponds to at least one set of data received from at least one user. The transmitter includes a modulating device that is configured to generate at least one signal that corresponds to the received message, wherein the signal includes at least one sequence of a plurality of hopping patterns. A receiver is coupled to the transmitter, wherein the receiver is configured to receive the signal. The receiver includes a demodulating device that is configured to identify the sequence of the hopping patterns and to determine at least one variable that corresponds to the sequence of the hopping patterns. The demodulating device is further configured to generate at least one output that is based on the determined variable, wherein the output is displayed such that at least one other user is enabled to view the output.
