Title: Fast adaptive power control for a variable multirate communications system
Inventor: HAIM JOHN W
IPC: H04B1/707
Filed: 2001-07-16
Granted: 2005-02-11
Abstract: A system and a method of controlling transmitter power in a wireless communication system in which user data is processed as multirate signal having a rate N(t) and in which the user data signal having rate N(t) is converted into a transmission data signal having a faster rate M(t) for transmission. The transmission power is adjusted on a relatively slow basis based on quality of data received by a receiver of the transmitted data. The transmitter power is determined as a function of N(t)/M(t) such that a change in the data rate in the multiple channels or the rate of the transmission data signal is compensated in advance of a quality of data based adjustment associated with such data rate change. Preferably, the user data signal having rate N(t) is converted into the transmission data signal having the faster rate M(t) by repeating selected data bits whereby the energy per bit to noise spectrum density ratio is increased in the transmission data signal.

Title: Bit rate control method of low delay video signal by using dynamic rate table
Inventor: TSAI JI-CHANG
IPC: H04N5/00
Filed: 2001-11-22
Granted: 2004-01-01
Abstract: The present invention provides a bit rate control method of low delay video signal by using dynamic rate table. The method is to design a dynamic rate table according to the parameters such as the degree of complication of the video image block, quantization parameters and encoding bit numbers. For each inputted image block, by using the summation of absolute difference and the allocated number of bits to search the dynamic rate table, the best quantization parameters can be found under the requirement of minimum difference between the estimated number of encoding bits and allocated number of bits, so as to quantize and encode the block, and use the encoded practical number of bits to update the dynamic rate table. Thus, the dynamic rate table is updated automatically after each image block is updated, thereby the statistical characteristics of the video image can be quickly captured, and the variation of image content can be tracked correctly, so as to accurately control the output bit rate of the video encoder and obtain a better image reconstruction quality. In addition, since the bit rate control processing of the present invention has only integer computation program, the computational function of bit rate control is greatly enhanced, and the cost of hardware circuit is greatly reduced, so that the whole computation can be completed easily.
