比特流
It may also be an analog signal such as a phone call or a video signal, digitized into a bit-stream for example using pulse-code modulation (PCM) or more advanced source coding (analog-to-digital conversion and data compression) schemes.
It juddered when play-ing "Deja Vu" with ffd-show dxva decoder. Deja Vu includes a raw PCM bit-stream. It was ok with ffd-show with soft-ware decod-ing, but Haali can decode Deja Vu with PCM audio and using ffd-show dxva for video.
For example, when a part of the channel bandwidth fades, frequency interleaving ensures that the bit errors that would result from those subcarriers in the faded part of the bandwidth are spread out in the bit-stream rather than being concentrated.
Inverting the bits of the 4-ary output symbols produces an output bit-stream with (G, I) -constraints as in the PRML (G, I) codes used in reverse-concatenation modulation systems.
Compressed digital image bit-stream transmitted over wireless channel must consider the effects of the channel noise.
数字图像经过压缩编码后通过无线信道传输,必须考虑信道中各种噪声对编码数据的影响。
To optimally exploit the bandwidth, an optimized bit-stream extraction method was proposed to give more priority to the enhancement layer of key frames than that of non-key frames.
Data errors in the compressed bit-stream, possibly due to transmission errors, can lead to errors similar to large quantization errors, or can disrupt the parsing of the data stream entirely for a short time, leading to "break-up" of the picture.
The reason why interleaving is used on OFDM is to attempt to spread the errors out in the bit-stream that is presented to the error correction decoder, because when such decoders are presented with a high concentration of errors the decoder is unable to correct all the bit errors, and a burst of uncorrected errors occurs.
The radio has a heterodyne receiver architecture with a low intermediate frequency (IF), which enables the IF filters to be integrated on-chip. The transmitter uses direct IQ-modulation with Gaussian-filtered bit-stream data, a voltage controlled oscillator (VCO) buffer, and a power amplifier.
此无线电设备具有带低中频 (IF) 的外差接收器结构,可在片内集成中频滤波器。发射器采用直接 IQ 调制,具有高斯滤波位流数据、电压控制振荡器 (VCO) 缓冲器和功率放大器。
