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.

摘要： Techniques for sending signaling information using hierarchical coding are described. With hierarchical coding, individual messages for users are encoded using multiple interconnected encoders such that (1) the message for each user is sent at a data rate suitable for that user and (2) a single multicast message is generated for the messages for all users. A base station determines data rates supported by the users and the code rates to achieve these data rates. Each data rate is determined by one or more code rates. Signaling information for the users is mapped to data blocks to be sent at different data rates. Each data block is then encoded in accordance with the code rate(s) associated with the data rate for that data block. A final coded block is generated for all users and transmitted. Each user performs the complementary decoding to recover the message sent to that user.

摘要： To perform time synchronization using spectral estimation, a receiver obtains a frequency response estimate for pilot symbols received on each set of frequency subbands used for pilot transmission. The receiver performs spectral estimation on frequency response estimates for different sets of subbands to obtain a measured arrival time for a transmission from a transmitter. The spectral estimation determines a dominant frequency component in the frequency response estimates and derives the measured arrival time based on this dominant frequency component. A time error between the measured arrival time and a desired arrival time is computed and possibly filtered. The filtered or unfiltered time error is scaled with a fixed or adjustable gain. A time adjustment is then generated based on the scaled time error and using linear and/or non-linear functions. The time adjustment is sent to the transmitter and used to adjust the transmit timing at the transmitter.
