摘要： A receiver is provided, which is adapted to receive MPE-FEC frames and to correct erroneous sections within a received MPE-FEC frame by detecting unreliable sections and storing in an erasure structure list ("ESL") table compressed data that includes the base address of each detected erroneous section, together with the respective section's size. The size of the ESL table may be fixed, or it may correlate, or dynamically change according, to the actual number of detected erroneous sections. The data stored in the erasure structure list may then be forwarded to a decoder to correct erroneous sections. The erroneous sections may be detected by using CRC, and the decoder may be a Reed-Solomon decoder. If the application data table of the MPE-FEC is error-free (or full of errors), in which case the erasure structure list is empty (or full), this means that no FEC reception and error corrections are required, because there are no sections to correct in the first case and the decoder is incapable of correcting too many sections in the second case. Therefore, the receiving circuitry, or at least the decoder, may be disabled to save battery power.
摘要翻译：提供接收器，其适于接收MPE-FEC帧并通过检测不可靠部分来校正接收到的MPE-FEC帧内的错误部分并将消息结构列表（“ESL”）存储在包括基地址每个检测到的错误部分，以及相应部分的大小。 ESL表的大小可以是固定的，或者它可以与检测到的错误部分的实际数量相关或动态地改变。存储在擦除结构列表中的数据然后可以被转发到解码器以校正错误的部分。可以通过使用CRC来检测错误部分，并且解码器可以是Reed-Solomon解码器。如果MPE-FEC的应用数据表是无错误的（或者是错误的），在这种情况下，擦除结构列表为空（或满），这意味着不需要FEC接收和纠错，因为有在第一种情况下没有要校正的部分，并且解码器在第二种情况下不能校正太多部分。因此，接收电路或至少解码器可被禁用以节省电池电量。

摘要： One or more parameters of a tuner of a receiver may be adjusted by generating for the receiver one or more control signals associated with one or more parameters and applying control signals to the tuner during a cyclic prefix (CP) period. The receiver may generate a control strobe in synchronization with the CP period wherein the control strobe essentially begins with the CP period and has duration preferably shorter than the duration of the CP period. The duration of the control strobe may be chosen such that the one or more control signals, after being applied to the tuner, each reaches its steady state before the CP period lapses. The adjusted parameters, alone or in combination, may be, for example, the gain of the low-noise-amplifier (LNA), the synthesizer's local frequency , the DC correction level , the power gain amplifier , and the I/Q error, and the like. The demodulator of the receiver may generate one or more of the control signals required for adjusting one or more parameters. One or more control signals may be determined according to previously received symbols/transmissions, and by determining the tuner's parameters to be adjusted based on the receiver's continued performance evaluations, and generating and applying the control signals to the tuner as a consequence of or in relation to these evaluations.
摘要翻译：可以通过为接收机生成与一个或多个参数相关联的一个或多个控制信号并且在循环前缀（CP）周期期间向调谐器应用控制信号来调整接收机的调谐器的一个或多个参数。接收机可以与CP周期同步地产生控制选通，其中控制选通基本上以CP周期开始，并且具有优选地比CP周期的持续时间更短的持续时间。可以选择控制选通的持续时间，使得在施加到调谐器之后，一个或多个控制信号在CP周期过去之前都达到其稳定状态。单独或组合的调整参数可以是例如低噪声放大器（LNA）的增益，合成器的本地频率，DC校正电平，功率增益放大器和I / Q误差，等等。接收机的解调器可以产生调整一个或多个参数所需的一个或多个控制信号。可以根据先前接收到的符号/传输来确定一个或多个控制信号，并且通过基于接收机的持续性能评估确定要调整的调谐器的参数，以及作为或相关的结果产生和应用控制信号到调谐器对这些评估。

摘要： A method includes, in a receiver that operates using multiple clock signals having respective clock frequencies, accepting a request to receive a target channel frequency. In response to the request, a set of preferred clock frequencies is calculated, which when applied by the receiver will cause the receiver to tune to the target channel frequency while satisfying a predefined criterion relating to interference caused by the clock signals. The target channel frequency is received by setting the clock signals to the preferred clock frequencies.

摘要： One or more parameters of a tuner (101) of a receiver (100) may be adjusted by generating for the receiver one or more control signals associated with one or more parameters and applying control signals (106) to the tuner during a cyclic prefix (CP) period. The receiver may generate a control strobe in synchronization with the CP period wherein the control strobe essentially begins with the CP period and has duration preferably shorter than the duration of the CP period. The duration of the control strobe may be chosen such that the one or more control signals, after being applied to the tuner, each reaches its steady state before the CP period lapses. The adjusted parameters, alone or in combination, may be, for example, the gain GLNA. of the low-noise-amplifier (LNA), the synthesizer's local frequency FLO, the DC correction level LDC, the power gain amplifier GPOA, and the I/Q error, and the like. The demodulator of the receiver may generate one or more of the control signals required for adjusting one or more parameters. One or more control signals may be determined according to previously received symbols/transmissions, and by determining the tuner's parameters to be adjusted based on the receiver's continued performance evaluations, and generating and applying the control signals to the tuner as a consequence of or in relation to these evaluations.
