Since the late fifties, Hou Ziqiang has been engaged in the research of acoustics and signal processing, in the sixties, he presided over the design of China's first offshore integrated sonar, and actively promoted the use of digital signal processing technology in sonar, in the seventies, he presided over the development of beam forming computer, etc. In the eighties, he presided over the development of the integrated sonar for submarines. In the 1980s, he was in charge of the development of integrated sonar for submarines. The above researches were awarded the prize of the National Science Conference, the first prize of the Academy of Sciences and the National Scientific and Technological Progress Award. During the 1980s and 1990s, he was the Secretary General of the Chinese Academy of Sciences and devoted himself to the reform of the scientific and technological system and the establishment and development of China's high-tech industry. In the mid-1990s, he returned to the front line of scientific research, closely tracked the international cutting-edge technology, and actively advocated digital technology, broadband communication technology and information consumer electronics products in China. 1994, he founded the Digital Signal Processing Engineering Center (DSP Center) at the Institute of Acoustics of the Chinese Academy of Sciences (CAS), which specializes in the development of digital consumer electronics products, new network communication equipment and other technologies, and developed VCD, DVD, digital TV, Internet data broadcasting multifunctional set-top boxes, etc. He also worked as an engineer at the Chinese Academy of Sciences (CAS). In 1997, he took the lead in advocating the construction of informationization infrastructure with broadband IP network technology, and in February 1999, on behalf of the Chinese Academy of Sciences and other organizations, he reported to the State Council on the implementation of China's high-speed Internet demonstration project, which was officially approved by the State Council, and the establishment of the China Netcom Corporation for construction and operation. In recent years, Hou Ziqiang has been engaged in the research of network communication development strategy and published a series of papers, proposing the development of broadband IP metropolitan area network, Ethernet access network and new 3G broadband wireless mobile Internet suitable for China's national conditions, which has promoted the development of China's broadband network.
Hou Ziqiang is both a scientist and a successful entrepreneur, he founded the first high-tech enterprise listed on the Shenzhen Stock Exchange of China Science and Technology Company Limited and the first listed high-tech company of the Chinese Academy of Sciences. The company broke the embargo in the 80's to develop and produce the Kangfa integrated circuit design workstations to equip the domestic design department, and then produced China's first nuclear magnetic *** vibration meter in medical equipment. 98 years Hou Ziqiang seized the opportunity to decide China's science and health company to produce cell phone cell phone, 99 years science and health cell phone in the country's first to enter the market with its own brand success, and become a major cell phone producers in the country.
Hou Ziqiang served as director of the Institute of Acoustics from 1993 to 1997, and also served as chairman of the Shenzhen Cogent Group of the Chinese Academy of Sciences and chairman of the board of directors of China Cogent Corporation. He intended to lead the transfer of the then Acoustics Institute into the Tech Health Group, but was ultimately unsuccessful due to opposition and resistance from the founders and actual operators of the Acoustics Institute. Subsequently, Hou Ziqiang was accused of utilizing his position as the director of the Institute of Acoustics to carry out personal vendettas and to physically persecute those in charge of the acoustics company who resisted and opposed the move by means of suspension and financial audits. These incidents have been festering in the Institute of Acoustics for many years and have not been effectively resolved. These stains on Hou Ziqiang also cast a shadow over his personal image, which is difficult to dissipate.
