摘要： A method includes receiving a symbol modulated with multiple bits according to a signal constellation including multiple constellation points. A soft metric is computed for a given bit in the symbol: A first constellation point closest to the received symbol according to a distance measure is found. A row or column of the constellation points, which is closest to the first constellation point according to the distance measure, and over which a value of the given bit is constant and is opposite to the value of the given bit in the first constellation point, is identified. At least the identified row or column is searched for a second constellation point that is closest to the received symbol according to the distance measure. The soft metric is calculated based on the first and second constellation points. The value of the given bit is reconstructed based on the soft metric.

摘要： A method includes receiving an input signal carrying transmitted values by a receiver, which includes a decision device that produces estimates of the transmitted values. The input signal is filtered using a forward filter to produce a forward-filtered signal, and the estimates of the transmitted values are filtered using a backward filter to produce a backward-filtered signal. The decision device is applied to a composite signal produced from the forward-filtered and backward-filtered signals, so as to produce the estimates of the transmitted values. An accuracy of the estimates of the transmitted values is assessed, and coefficients of the forward filter are adapted depending on the assessed accuracy.

摘要： A tuner for a wireless receiver is provided, which may include an input interface that is adapted to receive wireless signals, a mixer that is adapted to select a specific frequency from signals received at the input interface, and a controllable switch that is adapted to lead an output from the mixer towards a base-band unit of the receiver and to disconnect the output. The tuner may further include a controller which may be adapted to operate the controllable switch to disconnect the output of the mixer when the controller studies characteristics of the tuner and to reconnect the output of the mixer at other times. The studied characteristics may be associated with parasitic direct current voltages in the tuner, which may be associated with a low noise amplifier of the tuner, or programmable gain amplifier of the tuner or with both amplifiers. The controller may cause a compensation direct current voltage to be generated and applied to the mixer's output based on the ratio between programmed gain and actual/measured gain of the programmable gain amplifier.

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 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 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 or errors), in which case the erasure structure list is empty (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：提供接收机，其适于接收MPE-FEC帧并且通过检测不可靠部分来校正接收的MPE-FEC帧内的错误部分并将其存储在包括基站地址的擦除列表（“ESL”）表压缩数据中每个检测到错误部分，以及相应部分的大小。 ESL表的尺寸可以是固定的，或者它可以相关联，或者根据检测到的错误部分的实际数量动态地改变。存储在擦除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的应用程序数据表无错误（或全部或错误），在这种情况下，擦除结构列表为空（或错误），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，因为在第一种情况下没有要校正的部分，并且在第二种情况下解码器不能校正太多的部分。因此，接收电路或至少解码器可被禁用以节省电池电量。
