Problems solved by technology

[0004] However, some current systems either have a low information transmission rate (such as the baseband symbol rate of the Bluetooth system is only 1Mbps), or use a more complex modulation method (such as the OFDM method for high data rate applications in several WLAN systems) , making the cost too high

Embodiment Construction

[0023] Below in conjunction with embodiment the present invention is further described, in appendix figure 1 middle:

[0024] 1. Microprocessor or computer is the operating platform of frequency hopping pattern generator, communication protocol, baseband data decomposition and synthesis program and upper layer application software. Among them, the frequency hopping pattern generator, communication protocol, and baseband data decomposition and synthesis do not have a large amount of calculation, and only a general 16-bit or even 8-bit microprocessor can be competent. However, the complexity of the upper application software of different applications varies greatly. For more complex applications, such as being used as a Bluetooth LAN wireless access point, since the upper application software includes the TCP / IP protocol, and the microprocessor should be able to connect to the network adapter , so we consider choosing a high-speed 32-bit microprocessor, such as Motorola's MCF52...

Abstract

Broad band high speed transmission signal system using relative low speed chip is to set up multiple N corelated transmit and receive channels between source and sink to divide a "big file" be transmitted into N "small files" transmitted and receive in parallel, finally to be in composition to recover the original "big file", therefore increasing the transmitting speed by N times. The said deviceis composed of a micro-processor, frequency hopping graph generator, baseband data resolution and composition device, source and sink module, frequency hopping compositor, modem dynamic amplifier andtime division duplexes, making up multi-channels.

Description

1. Technical field: [0001] The invention relates to a system capable of high-speed broadband signal transmission by using a relatively low-speed chip, and belongs to the technical field of wireless communication. 2. Background technology: [0002] Internet and mobile communication have become the two fastest-growing fields in the information industry. Business integration and multimedia are the focus of communication business development. Broadband wireless multimedia communication is becoming a new hot spot. Due to the variety of information media and the huge amount of data, the demand for broadband and high-speed wireless multimedia transmission is becoming more and more obvious. Therefore, the transmission rate of the communication system must be high enough, which makes the contradiction between frequency resources and broadband high-speed applications and large capacity become more and more obvious. Any method that can solve these contradictions at low cost has great a...
