摘要： An apparatus and method for combining transponder bandwidths comprises a wide-band virtual transponder for transmitting a single data stream. The wide-band virtual transponder is comprised of a plurality of narrow-band physical transponders. A plurality of elementary streams are statistically multiplexed to create the single data stream, wherein the single data stream is forward error correction encoded and demultiplexed into a plurality of transponder streams for transmission by the plurality of physical transponders. The physical transponders each use a different portion of a signal spectrum, wherein the different portion may be guard bands or a combination of legacy bands and guard bands. Upon receipt, the transponder streams are multiplexed to recover the single data stream, wherein the recovered single data stream is forward error correction decoded and statistically demultiplexed to recover the plurality of elementary streams.

摘要： Various systems and methods are provided for channel estimation. These systems and methods (a) determine a coherence bandwidth for the channel, (b) adapt the channel estimation based on the coherence bandwidth, and (c) perform channel estimation by transmitting a channel estimation symbol over a channel. In some embodiments, the channel estimation is adapted based on the coherence bandwidth. This may include selecting a number of channel estimation symbols to transmit in a packet. Additionally, the number of channel estimation symbols transmitted in a packet can be selected by increasing the number of channel estimation symbols when the coherence bandwidth of the channel is high or decreasing the number of channel estimation symbols when the coherence bandwidth of the channel is low.

摘要： A first estimator determines a coarse estimate of a time of arrival of at least one subcarrier of an OFDM-like multitone signals by adjusting the coarse estimate of the time of arrival in accordance with a code (first) correlation function. A second estimator determines a precise estimate of the time of arrival of at least one subcarrier of the OFDM-like multitone signals by adjusting the precise time of arrival to align the slope of the subcarrier phases of the OFDM-like multitone signals in accordance with a phase (second) correlation function and consistent with the coarse estimate of the time of arrival associated with the code correlation function. A data processor estimates the location of the receiver or estimated range based on the precise estimate.

摘要： A telecommunications system is provided that can re-sample a digitized signal at a resample rate that is based on one or more factors to better utilize bandwidth. The factors can include the bandwidth of the signal that the digitized signal represents, the amount of bandwidth owned or used by the carrier, the full bandwidth of the designated RF band, the bandwidth of the serial link, the frame length of the serial link, the segmentation of the frames on the serial link, and the capability of the equipment at the receiving end of a serial link. The re-sampled signal can be transmitted to another unit that is remote to the unit transmitting the signal. The other unit can include a re-sampling device that restores the re-sampled signal to a digital signal that can be converted to an analog signal for wireless transmission.
