Abstract: A receiving unit 28 includes a tuner circuit board 100 that receives a first signal that may include a satellite signal. The tuner circuit board 100 demodulates the satellite signal to form a second signal. The second signal is provided to an internet protocol (IP) and control module circuit board 102 that is separated from the tuner circuit board 100. The internet protocol (IP) and control module circuit board 102 formats the second signal to form an IP encapsulated signal. The IP encapsulated signal is communicated to a device 44 so that a display 46 may be generated.

Abstract: The Energy spectral density of OFDM signals inherently rolls off slowly. Slow OFDM spectral rolloff has system level implications traditionally mitigated by some combination of the following: addition of bandlimiting filtering; use of significant guard bands of zeroed tones; and, guard time shaping. Each of these techniques negatively impact system performance and/or flexibility. This application presents a methodology for active cancellation of out of band spectral energy. The technique can be used by itself or in conjunction with above traditional methods to help control out of band emission. Examples of the use of the new technique are provided. Computational cost of the new technique is also discussed.
