Turbo code is a major breakthrough in the field of error correction coding in communication systems in recent years. He has won the favor of many scholars for its superior performance close to the Shannon limit. In this paper, the optimization algorithm based on Max-Log-Map is
Abstract: A video compression system based on TMS320DM6446 is designed. The main chip uses TI's TMS320DM6446, and the analog video signal is sent to the decoder TVP5150, which is decoded to conform to ITU-R BT. 656 standard digital video signal, BT. 656 digital video signal is sent to TMS320D
In the past few years, the practical application of small-volume high-precision and low-resistance resistors, as well as the significant increase in data acquisition and processor performance, have led to technological innovations in traditional shunt-based current sensing methods. New applicatio
1ZigBee Technology Introduction With the development of digital communication and computer technology, many short-range wireless communication requirements have been put forward. The network and standardization requirements for wireless technology are gradually appearing in front o
For us, all life is driven by electricity, especially home appliances, but it is inseparable from this electric tiger. However, the air-conditioning of large households in the home is also very confused. Many consumers always feel that the air conditioners in the home are always charged,
1 System Overview This design utilizes the powerful computing power of the DSP development board to implement a variety of information security algorithms that require a large number of operations. It realizes boot user authentication, voice confidential communication [1][2],
[High-tech LED News] It is reported that South Korea's two major electronics giants LG and Samsung are actively working on the development of 55-inch OLED prototypes using sub-era imaging technology, and hope to exhibit at the FPD International Exhibition in Japan next month. It is understood
First, the circuit characteristics description The RD-251 provides a single 350 mA constant current output at 12 V and 18 V LED string voltages. Using a standard AC mains thyristor dimmer reduces the output current to 1% (3 mA), which does not cause LED load performance to be unstab
