摘要： Method and apparatus for improving the channel estimate of a communication channel between a first station and a second station, while reducing the amount of reserved bandwidth for pilot tones. Hierarchical modulation is used to augment pilot density without sacrificing throughput. At the first station, a digital information stream may be split into a base stream and an enhancement stream, wherein the base stream and the enhancement stream combined form a hierarchical signal. At the second station, the base stream may be first recovered, and recovered base stream serves as a pilot for the enhancement stream. Thus the base stream, which is a subset of the total transmitted information, may be made to perform the channel-sounding function for the enhancement stream.

In an embodiment, a replica circuit (220) having substantially the same topology and sizing as a push-pull amplifier circuit is coupled to a main push-pull amplifier circuit (200). A transistor (MPlR) in the replica circuit (220) may be biased using feedback to generate a predetermined DC output voltage level, and such bias level may be applied to a corresponding transistor (MPl) in the main push-pull amplifier circuit (200). In another embodiment, a transistorMnlB) in a current bias module (210) may be used to bias corresponding transistorsMnl, MnPR) in the main push-pull amplifier circuit (300) and the replica circuit (220). Further techniques are disclosed for configuring the amplifier to have a non-uniform step size with finer resolution at lower power levels and coarser resolution at higher power levels to reduce power consumption at lower power levels.

摘要： Techniques for performing channel estimation in a multi-carrier system are described. A frequency response estimate is initially obtained for a wireless channel based on a narrowband pilot sent on different sets of subbands in different symbol periods or a wideband pilot sent on all or most subbands in the system. Spectral estimation is performed on the frequency response estimate to determine at least one frequency component of the frequency channel estimate, with each frequency component being indicative of a delay for a channel tap in an impulse response estimate for the wireless channel. A channel estimate for the wireless channel is then obtained based on the frequency component(s) determined by the spectral estimation. This channel estimate may be a channel profile, the impulse response estimate, an improved frequency response estimate, a signal arrival time, or some other pertinent information regarding the wireless channel.
