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： A method of processing a DAB audio stream, the method comprising: receiving a compressed and modulated DAB audio stream comprising a plurality of audio frames encoded with scale factors and a DAB-CRC error detection code for indicating errors in the scale factors; demodulating the DAB stream; and processing the demodulated and still compressed DAB stream responsive to the DAB-CRC of at least one audio frame of the plurality of audio frames; by determining a trend in values of scale factors and repairing or concealing the error in the scale factor responsive to the trend.

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.
