摘要： In one embodiment, a satellite radio receiver is capable of simultaneously processing (i) a first radio channel that is playing on a first speaker and (ii) a second radio channel, different from the first radio channel, that is not playing on the first speaker. The second radio channel can simultaneously be playing on a second speaker, be recorded onto a non-volatile memory, and/or have its processing modified. A user can control the satellite radio receiver using vocal commands, while the first channel is playing on the first speaker. The radio receiver has a microphone connected to a voice-recognition command interpreter that includes an interfering-sound canceller, which reduces sounds interfering with the vocal commands, and a command-recognition module, which recognizes vocal commands and provides a control signal to a multi-channel control processor, which processes and controls the first and second radio channels, received from corresponding decoders connected to a satellite radio receiver antenna.

摘要： An improved multi-channel receiver for satellite broadcast applications or the like. In an exemplary embodiment, the receiver has an adaptive equalizer configurable to operate with QPSK or 8PSK modulated signals. In the equalizer, a slicer table memory responsive to an 8-level quantizer (slicer) and a select signal is configured to map the output of the quantizer into QPSK or 8PSK symbol coordinates depending on whether the QPSK or the 8PSK signal is being received. The slicer table memory may be loaded with the symbol coordinates calculated from data in the 8PSK signal. A pattern matcher determines if the 8PSK or the QPSK signal is being received and asserts the select signal to configure the slicer table memory accordingly.

摘要： A back-up solution is presented for a DSL modem that guarantees essentially uninterrupted data connections in the event of a failure in the DSL connection. When a DSL data connection fails, e.g., due to changes of the local loop characteristics in the high frequency band, a voice-band modem is used in conjunction with an amplitude modulator/demodulator to keep the data connection uninterrupted by shifting the voice-band modem signal up to DSL frequencies, transmitting the data at this higher frequency over the local loop between the subscriber and a DSLAM, and then shifting the voice-band modem signal back to a “normal” frequency and demodulating this signal using the voice-band modem before it enters the data network. Since the frequency band used is at a frequency higher than that of voice communications, the subscriber can continue to use the local loop to conduct voice communications or any other communications that require use of the voice band frequencies, such as facsimile and V. series modem communications.
摘要翻译：为DSL调制解调器提供了备份解决方案，可在DSL连接发生故障的情况下保证基本上不间断的数据连接。当DSL数据连接失败时，例如，由于高频带中的本地环路特性的变化，语音频带调制解调器与幅度调制器/解调器结合使用，以通过移动语音带来保持数据连接不间断调制解调器信号直到DSL频率，通过用户和DSLAM之间的本地环路以更高的频率发送数据，然后将语音频带调制解调器信号转换回“正常”频率，并使用语音频带解调该信号调制解调器进入数据网络之前。由于所使用的频带的频率高于语音通信的频率，用户可以继续使用本地环路进行语音通信或需要使用语音频带频率的任何其他通信，例如传真和V.系列调制解调器通讯。

摘要： An improved multi-channel receiver for satellite broadcast applications or the like. In an exemplary embodiment, a primary AGC loop controls an analog sub-receiver adapted to simultaneously receive multiple signals. Multiple digital demodulators, coupled to the sub-receiver, demodulate the multiple received signals. Multiple secondary AGC loops, one for each received signal, compensate for variations in demodulated signal strengths caused by the primary AGC loop. A feed-forward AGC compensation technique generates scalar control values for scaling the demodulated signals before the demodulated signals are processed by the secondary AGC loops. This at least partially compensates for gain variations caused by the primary AGC, reducing received signal drop-outs before the secondary AGC loops can compensate for the gain variations. Because of systemic delays in the sub-receiver and the demodulators, the scalar control values are independently timed to be coincident with the variations in the demodulated signal strengths caused by the primary AGC loop.
