摘要： A method and apparatus for estimating whether or not a wireless terminal is indoors are disclosed. The illustrative embodiment employs a pattern classifier that is trained on a plurality of input/output mappings, where each mapping corresponds to a respective location, the output of the mapping is a Boolean value that indicates whether the location is indoors, and the input of the mapping is based on empirical and predicted signal data for the location. In accordance with the illustrative embodiment, a computer-executable program is generated based on the trained pattern classifier. The computer-executable program estimates whether or not a wireless terminal is indoors based on empirical data reported by the terminal, and on a location estimate for the terminal that might be crude or inaccurate (e.g., based on Cell Identifier [Cell-ID], GPS, etc.).

摘要： An OFDM transmitter that performs a peak reduction process in a stepwise manner on a signal sequence to be transmitted. The transmitter includes a dividing IFFT unit that divides a signal sequence into a plurality of signal sequences and IFFTs each of the signal sequences to obtain time signal sequences. Then, a first peak reduction processing unit cyclically shifts a first one of the time signal sequences by a first amount of cyclic shift obtained based on a first threshold to obtain a first cyclically shifted time signal sequence, and adds the first cyclically shifted time signal sequence and a second one of the time signal sequences. Meanwhile, a second peak reduction processing unit cyclically shifts a third one of the time signal sequences by a second amount of cyclic shift obtained based on a second threshold to obtain a second cyclically shifted time signal sequence.
