Abstract: The exercise and training apparatus includes: A base disposed on a supporting surface for the apparatus. An upper body support arrangement secured to the base frame in a manner that allows several positions from generally horizontal position to a generally vertical position. A lower body support arrangement secured to the base frame adjacent to the upper body support having a generally horizontal position. A head support secured to the upper body support arrangement. A pair of hand levers attached to the upper body support one on each side in a manner that allows the user's hands to move the levers in plural directions. A lever secured to the lower body support arrangement capable of receiving the user's legs in a manner that allows the user to move the lever in plural directions. An adjustable resistance device secured to each lever in order to provide resistance to movement of the lever.

Abstract: Methods and apparatus are disclosed for DC offset estimation and for DC offset compensation that collectively reduce or eliminate the distortion of subcarriers due to DC offset in an OFDM receiver. The DC offset estimation is obtained by subtracting a sum of time domain samples of an OFDM symbol for two consecutive OFDM symbols or subtracting a known transmitted OFDM symbol and a frequency domain representation of a received version of the known OFDM symbol (at least one of which is adjusted to compensate for channel distortion). The DC offset compensation is accomplished by removing the estimated DC offset from the received signal. The DC estimation process and the DC compensation process can be connected in disclosed feed-forward or feedback configurations.
