摘要： Methods and apparatuses are provided for reducing a Peak to Average Power Ratio (PAPR) in a digital broadcasting system. Reserved tones are determined in previously determined locations of sub-carriers that do not collide with a pilot signal of a preamble in a frame. A signal is transmitted through the reserved tones in a period for which the preamble is transmitted. If a Fast Fourier Transform (FFT) size is 8K, locations of the reserved tones are determined in accordance with a specified chart.

摘要： The present disclosure includes systems and techniques relating to wireless devices. A described technique includes generating respective frequency segments of a composite signal which are contiguous in a frequency domain, each of the respective frequency segments being based on a segment bandwidth; applying respective cyclic shift delay (CSD) phase shifts to the respective frequency segments to produce respective output signals; and transmitting the composite signal by transmitting signals that are based on the respective output signals. The respective CSD phase shifts, including first and second CSD phase shifts, are equivalent to third CSD phase shifts that correspond to a contiguous non-composite signal having a single frequency segment. A bandwidth of the single frequency segment is at least twice the segment bandwidth. The respective CSD phase shifts are applied such that a device receiving the composite signal uses the third CSD phase shifts that correspond to the contiguous non-composite signal.

摘要： Multi-channel support within single user, multiple user, multiple access, and/or MIMO wireless communications. A communication device is implemented to encode information bit(s) to encoded bits, which subsequently can undergo processing by an interleaver that is implemented to generate interleaved bits. A constellation mapper is implemented to map the interleaved bits to constellation(s) to generate mapped signals. Two or more inverse discrete fast Fourier transform (IDFT) processors are respectively implemented to process the mapped signals to generate signal streams. For example, a first IDFT processor is implemented to process a first of the mapped signals to generate a first signal stream, and a second IDFT processor is implemented to process a second of the mapped signals to generate a second signal stream. Such a communication device also includes communication interface(s) to transmit the signal streams to at least one additional communication device.

摘要： A method of identifying radar in a wireless device includes detecting an event corresponding to receipt of a signal by the wireless device. The event can include an analog to digital converter (ADC) saturation, a radio frequency (RF) saturation, and/or an ADC power high condition. Notably, the gain change in the wireless device is delayed for a first predetermined time period. Data preceding the event for the first predetermined time period can be buffered. A first low-resolution fast Fourier transform (FFT), wherein low-resolution FFTs are referred to as short FFTs, can be performed with the buffered data. The first short FFT can be processed. When results of the processing indicate the signal is radar, the radar can then be identified.

摘要： In one embodiment, a transmitter converts digital input data into combined-OFDM signals and a receiver recovers data from the transmitted combined-OFDM signals. For transmission, digital data is mapped into data symbols using a commonly known modulation technique, such as QAM or DQPSK. The data symbols are subsequently divided into two or more groups according to a specified grouping pattern. Each group of data symbols is then converted into a separate OFDM subsymbol using IFFT processing. The OFDM subsymbols are then combined according to a specified combining pattern to create a combined-OFDM symbol. Combined-OFDM symbols are then prepared for transmission by affixing cyclic prefixes, converting the symbols to analog format, and performing spectral shaping of the analog signal. Upsampling may be employed to increase the signal bandwidth. In alternative embodiments, OFDM subsymbols may be combined using interleaving to create an interleaved-OFDM symbol.
摘要翻译：在一个实施例中，发射机将数字输入数据转换为组合OFDM信号，并且接收机从所发送的组合OFDM信号中恢复数据。为了传输，使用公知的调制技术（例如QAM或DQPSK）将数字数据映射成数据符号。数据符号随后根据指定的分组模式分成两组或更多组。然后使用IFFT处理将每组数据符号转换成单独的OFDM子符号。然后根据指定的组合模式组合OFDM子符号以创建组合OFDM符号。然后通过附加循环前缀，将符号转换为模拟格式，并执行模拟信号的频谱整形，准备组合OFDM符号进行传输。可以采用上采样来增加信号带宽。在替代实施例中，可以使用交织来组合OFDM子符号以创建交错OFDM符号。
