coding gainの例文

• STBCs offer only diversity gain ( compared to single-antenna schemes ) and not coding gain.
• Bits from the subordinate pass are usually random enough that entropy coding provides no further coding gain.
• This is contrast with space time trellis codes which provide both diversity and coding gain since they spread a conventional trellis code over space and time.
• Iterated decoding is now also applied to serial concatenations in order to achieve higher coding gains, such as within serially concatenated convolutional codes ( SCCCs ).
• Balderas : " Our next steps are to ensure that the Code gains worldwide acceptance and becomes an integral part of how the industry operates and how governments and clients select security providers.
• This scheme reportedly has high coding gain for low bit rate and potential robustness against channel errors and packet loss, since it does not use any variable length coding and adaptive bit allocation.
• In contrast to space time block codes ( STBCs ), they are able to provide both coding gain and diversity gain and have a better Viterbi decoder at the receiver where STBCs need only linear processing.
• For the special case of a binary linear block code C with parameters ( n, k, d ), the nominal spectral efficiency is \ rho = 2k / n and the nominal coding gain is " kd " / " n ".
• This is done both to increase coding gain ( the L-R channel can typically be heavily compressed, and the subsequent un-matrixing will cause many compression artifacts to cancel ), and to preserve phase relationships necessary for proper playback of Dolby Surround-encoded material.
• The symbol rate is identical to that of 100BASE-TX ( 125 megabaud ) and the noise immunity of the five-level signaling is also identical to that of the three-level signaling in 100BASE-TX, since 1000BASE-T uses four-dimensional dB coding gain across the four pairs.
• In addition to the two-stage transform, a different bit-allocation structure is used, and two ways of representing encoded mantissas are deployed : use of vector quantization, which gives the highest coding gain, and use of gain-adapted quantization ( GAQ ) when greater signal-fidelity is required.
• In coding theory and related engineering problems, "'coding gain "'is the measure in the difference between the signal-to-noise ratio ( SNR ) levels between the uncoded system and coded system required to reach the same bit error rate ( BER ) levels when used with the error correcting code ( ECC ).
