After
bit allocation based on (4), the supported modulation order for Alamouti coding system is calculated by summing bits over subchannels of one SISO channel.
In [9], a subcarrier and
bit allocation scheme is obtained with a goal of minimizing the overall transmit power while meeting a constant bit-rate.
The
bit allocation for the image with the size of 8x8 pixels is shown in Figure 1.
The
bit allocation using three kinds of preequalization is shown in Figure 11.
While these rate control algorithms in stereo/multiview video coding made useful explorations, however, these algorithms were only designed to frame layer
bit allocation. In order to more finely rate control, it is necessary to develop the rate control techniques on the MB layer.

bit allocation with adaptive cell selection for OFDM systems", IEEE.
The quality of subject faces is further enhanced by the newly developed
Bit Allocation. The camcorder allocates more encoding bits on the detected face area than other parts of the picture so that a high quality and clear face can be recorded.
[6] consider an optimal two-pass frame-layer
bit allocation scheme for H.264 video.
Other topics include a Langrangian formulation of fixed-rate quantization, error concealment for dual frame video coding with uneven quality, JPEG 2000 content analysis using codestream length information, and fast pre-computed VQ with optimal
bit allocation for lossless compression of ultraspectral sounder data.
To better address the issues mentioned above, we attempt to achieve more accurate
bit allocation and keep consistent object video quality with a different approach for HEVC in this paper.
Other studies have focused on resource allocation for OFDMA networks: in [5], the resource allocation problem is effectively approached with a chunk-based resource allocation scheme, that is, optimal chunk, power, and
bit allocation. A digitization process is proposed by considering the digital nature of bits/symbol/subcarrier, which leads to better average throughput of this dynamic power allocation compared to the fixed power allocation scheme.
ABSTRACT: In this work, the frame-layer
bit allocation problem is studied for H.264 video.
