摘要： A method for detecting a preamble location in a multiple preamble OFDM (Orthogonal Frequency Division Multiplexing) system is disclosed. An OFDM signal is generated with a plurality of frames, and each of the frames includes symbols and a predetermined preamble symbol. A maximum FDDC (Frequency Domain Differential Correlator) value is computed for each of the symbols in some of the frames. The preamble location in a frame is determined by summing the maximum FDDC value for each symbol at a same frame location in consecutive frames of the OFDM signal.

摘要： A wireless device and method of power consumption reduction are generally described herein. The wireless device may map a plurality of data symbols to sub-carriers for an orthogonal frequency division multiplexing (OFDM) transmission. The wireless device may divide the plurality of data symbols into first and second groups of data symbols. The wireless device may generate a first OFDM signal from the first group of data symbols for amplification by a first power amplifier (PA). The wireless device may generate a second OFDM signal from the second group of data symbols for amplification by a second PA. The data symbols of the first and second groups may be selected to provide a PAPR of the first OFDM signal that is lower than a PAPR of a composite OFDM signal based on the plurality of data symbols.

摘要： Embodiments of methods and systems for auto-correlating wireless signal samples are provided. Such embodiments include local normalization of each signal sample by a root mean square level of samples that preceded it, prior to any summation of the auto-correlation procedure. These auto-correlated signal samples are then used to distinguish downlink from uplink signals present within the signal sample set. Other embodiments include auto-correlation techniques in which no normalization is performed at any time with respect to the summation procedure. Such auto-correlated samples are then scanned to detect a preamble symbol or symbols within the signal samples. Reliable and expeditious wireless communications under WiMAX 802.16e and other protocols can be achieved in accordance with the present embodiments.
