  The President and CEO of the   American Semiconductor Industry Association (SIA) , John Neuffer, stated at the China Development Forum that the chip industry is highly dependent on the global supply chain. No country can fully automate the chip supply chain. The government should reduce restrictions on the export of chip technology and increase investment in basic research to promote innovation in the semiconductor industry. The American Semiconductor Industry Association represents more than 98% of the semiconductor industry companies in the United States. Neuffer said that semiconductors are the second largest global trade volume industry after petroleum, and an industry that truly relies on a  globalized supply chain . "The semiconductor industry shoulders a heavy responsibility. Whether it is traditional industries such as energy, transportation, and medical care, or emerging industries such as AI, wireless networks, and quantum technology, they all rely heavily on...

Market research firm Gartner recently released its 2020 revenue forecast for the semiconductor industry. According to Gartner's forecast, the revenue scale of global semiconductor manufacturers in 2020 will reach the US $449.838 billion, a year-on-year growth of 7.3%. "At the beginning of 2020, the Coronavirus (Covid-19) pneumonia outbreak was thought to hurt all end device markets, but the actual impact was minimal," said Andrew Norwood, research vice president at Gartner. Certain segments of the auto, industrial and consumer markets have been hit by a drop in business and consumer spending. However, the market benefits from home isolation, which dramatically increases the time spent at home and online." "Server demand is strong as super-scale customers (accounting for more than 65% of server demand in 2020) rush to add capacity to cope with additional demand during the lock-in period in the first half of 2020. Besides, strong corporate and consumer demand for ...

Software Radio, a systematic structure to realize wireless communication launched in recent years, is a significant breakthrough in the field of wireless communication in the wake of analog to digital communication, fixed to mobile communication. The basic principle of it is that the received analog signal is digitalized as soon as possible, and various functions of the radio are realized by software to the most extent. Software Radio is an open structure to realize all types of wireless communication systems through a general hardware platform and then through software loading. For Software Radio, the digitalized hardware platform is the basis, the programmable and reusable software is the core, and realizing multi-band,  multi-system, and universal reception is the goal. Figure 1 is the block diagram to realize Software Radio. Figure 1 shows the four-carrier communication system. The traditional simulation structure completes the conversion from RF(Radio Frequency) to IF(Intermed...
