Problems solved by technology

However, these technologies cannot be used in WiMAX (Worldwide Interoperability for Microwave Access) systems with bandwidths varying from 5MHz to 20MHz
In addition, existing schemes for transmitting wireless signals over wired transmission media are strictly limited by the maximum transmission distance, which limits their applications
[0005] WiMAX (20MHz) and future wireless communication systems have a wide spectrum, so existing solutions cannot meet the requirements of both transmission bandwidth and transmission distance

Embodiment Construction

[0025] Fig. 1 shows a method for transmitting a signal via a wired transmission medium in a sending device (or sending module) and a receiving device (or receiving module) of a signal transmission device of a communication network according to a specific embodiment of the present invention, The sending device and the receiving device of the signal transmission device respectively treat the processing process of one original signal sequence to be sent and the received multi-channel bandwidth-compressed sub-signal sequences.

[0026] For the original signal sequence to be sent, the sending device in the signal transmission device expands its sampling interval, so that the period of the original signal sequence (period T, bandwidth W) is doubled (period becomes 2T), Then its bandwidth is correspondingly compressed to the original 1 / 2 (the bandwidth becomes W / 2), and then, the above-mentioned processed signal sequence is divided into two sub-signal sequences, which are respectively...

Abstract

The invention features the following: compressing the signals to make the signal capable of being transmitted on category 5e twist-pair; namely, the one route of signals on sending end are divided into multi routes of wideband compressed sub-signals which are synchronously transmitted on wired media in multi parallel routes; the receiving end receives each route of signals, and restores it to one route of original signals.

Description

technical field [0001] The invention relates to a communication network, in particular to a method and a device for extending a coverage range by using a wired transmission medium to transmit signals in a wireless network. Background technique [0002] The rapidly increasing number of mobile users and numerous high-rise buildings in the city make the communication density increase day by day, and users' requirements for network coverage capabilities continue to rise. These modern buildings are large in scale and of good quality, and have a strong shielding effect on wireless signals. In some places inside large buildings, the wireless communication signal is weak, and the mobile terminal cannot be used normally, forming a blind area and shadow area of ​​mobile communication; the indoor coverage system is produced under this background. [0003] Existing solutions for transmitting wireless signals on wired transmission media (such as copper wires) are mainly aimed at the ind...
