摘要： Techniques for detecting and demodulating a signal/transmission are described. Signal detection is performed in multiple stages using different types of signal processing, e.g., using time-domain correlation for a first stage, frequency-domain processing for a second stage, and time-domain processing for a third stage. For the first stage, products of symbols are generated for at least two different delays, correlation between the products for each delay and known values is performed, and correlation results for all delays are combined and used to declare the presence of a signal. For demodulation, the timing of input samples is adjusted to obtain timing-adjusted samples. A frequency offset is estimated and removed from the timing-adjusted samples to obtain frequency-corrected samples, which are processed with a channel estimate to obtain detected symbols. The phases of the detected symbols are corrected to obtain phase corrected symbols, which are demodulated, deinterleaved, and decoded.

摘要： A method and apparatus estimate an offset between a carrier frequency of a transmitter and a local reference frequency of a receiver. A received signal is separated into frequency synchronization signals and data, and a determination is made whether the frequency synchronization signals are adequate for estimating the frequency offset. This determination may be made based on, e.g., an estimated Doppler spread, an estimated signal to noise ratio, and/or an available amount of frequency offset estimation time. The frequency offset is estimated based on the determination results. If the frequency synchronization signals are adequate for estimating the frequency offset, the frequency synchronization signals are used for determining the frequency offset. Otherwise, the rate of the frequency synchronization signals is increased, e.g., by using the data as frequency synchronization signals, in which case the data is combined with the frequency synchronization signals to determine the frequency offset.

摘要： A system and method for synchronizing two devices in communication with each other. When communication between the two devices is to be established, a synchronization process may be invoked. In an embodiment, a first device may initiate sending synchronization signals having rising edge and falling edge pairs. The second device may include a controller configured to receive the synchronization signals. However, noise may inhibit the ability of the controller to correctly receive and/or interpret the synchronization signals. Noise may cause detection components to falsely detect noise as a synchronization signal or may cause detection components to miss detection of an actual synchronization signal. A window generator may be used to generate comparison windows for the controller to detect synchronization signals. Further, the detection window duration and start times may be adjusted based on previously detected (or undetected) synchronization signals in order to compensate for noise overshadowing synchronization signals.
