20140177741 | OFDM or OFDMA signaling for ranging and data - A communication device is operative to generate and orthogonal frequency division multiplexing (OFDM) symbol that includes one or more data and ranging modulation symbols. The data and ranging modulation symbols may be included within different sub-carriers of the OFDM symbol. The OFDM symbol is used to generate an OFDM symbol pair in the frequency domain (FDOM). After conversion from the FDOM to the time domain (TDOM), the OFDM symbol pair may then undergoes post-processing in the TDOM before transmission. Such post-processing may include the addition of cyclic prefix (CP) and cyclic suffix (CS) to the OFDM symbol pair in the TDOM as well as filtering using a window function. The OFDM symbol may be generated as an orthogonal frequency division multiple access (OFDMA) symbol, and two were more OFDM symbols or OFDMA symbols may be arranged in a frame. | 06-26-2014 |

20140233679 | Rceiver with Reduced Wake-up Time - An auxiliary reduced power analog-to-digital converter (ADC) is provided for use during sleep periods of a receiver. The auxiliary ADC has a reduced dynamic range but sufficient accuracy to allow demodulation of signaling information contained in an input signal and to update control parameters used for synchronization and channel estimation. As such, a main higher power, higher dynamic range ADC can be turned off during sleep periods, reducing receiver power consumption. The main ADC is turned on at the end of a sleep period, and the receiver can be ready for receiving data immediately using the main ADC because the control parameters are maintained up to date during the sleep period using the auxiliary ADC. | 08-21-2014 |
