Description

technical field [0001] The invention belongs to the technical field of wireless communication. In particular, it relates to a high-speed digital signal integrated processing device for wireless communication. Background technique [0002] With the development of science and technology, wireless communication technology has been widely used in people's daily life, and the emergence of software radio technology makes wireless communication enter the era of digital signal processing. For civil satellite communication, radar signal processing and other high-speed data processing applications with high technical requirements and fast processing speed, the digital signal processing platforms for wireless communication in domestic and foreign markets can no longer meet the requirements. At the same time, many applications require a wider bandwidth of receiving and transmitting signals, and users can develop and verify their own wireless communication digital signal processing alg...

Problems solved by technology

[0003] Generally speaking, similar products at home and abroad have the following shortcomings: the data acquisition bandwidth and processing bandwidth are not enough; the high-speed A / D and D / A chips on the digital receiver cannot achieve maximum utilization, and the speed of processing chips in many digital transceivers cannot keep up The maximum speed of these high-speed A / D and D / A chips, that is, when these A / D and D / A chips are converted at the highest speed, the processing chip cannot reach this speed; the speed of high-speed A / D and D / A chips of many platforms Although it has been achieved, its conversion accuracy cannot reach satisfactory accuracy; many platforms have insufficient resources to realize key signal processing functions such as modulation, demodulation, synchronization, and FFT, which limits the scope of application of the product; existing processing platforms There are deficiencies in power consumption, engineering practicability, etc.

Its shortcoming is that the invention patent application technology cannot perform high-speed data processing of wireless communication, A / D data acquisition may have speed or data processing bottlenecks, and large-scale high-speed modulation, demodulation, synchronization, and FFT cannot be realized And other key signal processing functions, it is impossible to form a high-speed processing array, so that the comprehensive optimization processing of key signals cannot be realized at critical moments, and its power consumption and engineering practicability are not strong
