摘要： A satellite direct radio broadcast system is provided which assembles bits of broadcast programs into prime rate increments, several of which are assembled into a frame. Frames are divided into symbols which are demultiplexed into alternating ones of a plurality of prime rate channels. The prime rate channels are demultiplexed onto a corresponding number of broadcast frequencies for transmission to a satellite. The satellite payload switches the symbols into time division multiplexed (TDM) data streams. The receivers process the TDM streams using service control headers (SCHs) provided therein by broadcast stations. The SCHs facilitate transmission of different service components within broadcast channel frames, association of a primary broadcast channel with one or more secondary broadcast channels on a frame-to-frame basis, and the transmission of multiframe bit streams, or auxiliary data throughout a broadcast channel that are independent of a service, in contiguous or non-contiguous frames.

摘要： A satellite payload processing system for processing an uplink signal consisting of a plurality of single-channel-per-carrier, frequency division multiple access carriers comprises a polyphase demultiplexer processor for separating the uplink signal into a time division multiplexed data stream of symbols. The polyphase demultiplexer processor presents the symbols corresponding to each of a plurality of carriers at respective ones of the frequencies in the uplink signal sequentially to an output of the polyphase demultiplexer processor. A phase shift keying demodulator and differential decoder demodulates the stream of symbols into corresponding time division multiplexed stream of digital baseband bits, which are then rate-aligned with respect to an on-board clock.

摘要： A method of receiving one of a plurality of prime rate channels transmitted via downlink signals from a satellite comprises the step of demodulating downlink signals into a baseband time division multiplex bit stream comprising frames generated by the satellite. Each of the frames comprises a plurality of time slots, each of the time slots having a set of symbols. Each symbol in the set of symbols corresponding to a respective one of the prime rate channels occupies a similer symbol position in each of the time slots. The method further comprises the steps of locating the frames in the bit stream using a master frame preamble inserted therein by the satellite, and retrieving from the set of symbols in each of the time slots of at least one of the frames the symbols that correspond to one of the prime rate channels.

摘要： A satellite direct radio broadcast system is provided which assembles bits of broadcast programs into prime rate increments, several of which are assembled into a frame. Frames are divided into symbols which are demultiplexed into alternating ones of a plurality of prime rate channels. The broadcast channel frame is encoded for forward error correction (FEC) using an R-½ Viterbi coder or a R-¾ Viterbi coder, depending on the desired bit rate for a time division multiplexed (TDM) stream comprising the broadcast channel. A broadcast station is configured to format FEC-encoded broadcast channel frames into TDM frames when transmission of the TDM frames by a transparent payload on-board a satellite is used.

摘要： A system for managing a satellite and a number of broadcast stations, which generate programs for transmission to remote radio receivers on broadcast channels via the satellite, comprises a satellite control system for controlling the attitude and orbit of the satellite and on-board processing of the programs uplinked to the satellite. A broadcast control system is connected to the satellite control center and to the broadcast stations. The broadcast control system assigns selected ones of the broadcast channels to service providers desiring to uplink at least one of the programs to the satellite, to store channel data relating to the assignments of the broadcast channels and provide the channel data to the satellite control system, and to bill the service providers according to the number of the broadcast channels assigned thereto. The broadcast control system provides the service providers with a plurality of options comprising the number of said broadcast channels to be reserved for uplink transmission, dates and times of day for using the reserved broadcast channels, and which of a number beams associated with the satellite are to be used for downlink transmission. The broadcast control system notifies the satellite control system as to which of the beams are to be used and when, and the satellite control system generates corresponding data processing signals for routing the program to selected ones of the beams.

摘要： A satellite clock system in which the frequency of the onboard satellite clock, which is implemented as a relatively high uncertainty voltage-controlled oscillator, is corrected in accordance with a high-stability, low-uncertainty terrestrial clock. Metering bursts are transmitted from the earth station to the satellite where portions of the metering bursts are truncated due to misalignment between the bursts and the synchronization windows timed by the onboard oscillator of the satellite. The patterns of the received bursts which are re-transmitted by the satellite are compared with a stored pattern and a phase shift value determined in accordance with the number of incorrect comparisons. The phase error measurement value is utilized to control a programmable divider connected between the high-stability, low-uncertainty oscillator and the burst transmitter to thus provide a short-term correction. The output values from the phase error measurement are accumulated over a sidereal day period to provide a sidereal day phase shift value. The accumulated value of the sidereal day phase shifts is summed with all previous daily values to compute a cumulative phase shift from the beginning of the system operation. The current and cumulative phase shift values are then summed and divided by a period of one sidereal day to produce an actual phase correction for the next sidereal day. The actual daily frequency correction is computed by summing all values of the sidereal day frequency correction and telemetering this value to the satellite. Alternately, the accumulation of the frequency corrections can be performed onboard the satellite.

摘要： A satellite system employing time diversity and a single frequency network of terrestrial re-radiation stations is provided wherein each terrestrial re-radiation station inserts a delay into a terrestrial signal. The delay allows the time of arrival of the early time diversity signal at the center of terrestrial coverage to coincide with the arrival of the corresponding late time diversity signal, thereby improving hand-off between terrestrial and satellite signals at a receiver. The delay also adjusts for distance differences between each terrestrial re-radiation station and the satellite and between each station and the center of the terrestrial coverage region. This adjustment optimizes the TDM-MCM reception by synchronizing at the center of the SFN the phase of the MCM signals re-radiated from the re-radiating stations of the SFN. The delay also compensates for the processing delay encountered when converting a satellite LOS TDM stream into a multicarrier modulated stream for transporting the satellite LOS TDM stream to user receivers and for the diversity delay between the early and late signals.
摘要翻译：提供了一种采用时间分集的卫星系统和地面再辐射站的单频网络，其中每个地面再辐射站将延迟插入到地面信号中。延迟允许在地面覆盖中心的早期分集信号的到达时间与相应的后期分集信号的到达一致，从而改善接收机处的地面和卫星信号之间的越区切换。延迟还可以调整每个地面再辐射站与卫星之间以及每个车站与地面覆盖区域中心之间的距离差异。该调整通过在SFN的中心同步从SFN的再辐射站重新辐射的MCM信号的相位同步来优化TDM-MCM接收。该延迟还补偿了将卫星LOS TDM流转换成用于将卫星LOS TDM流传送到用户接收机的多载波调制流以及早期和晚期信号之间的分集延迟时遇到的处理延迟。
