Frequency selective mode single carrier blocking transmission method

Abstract

This invention provides a single-carrier blocking transmission method of frequency selective mode including the following steps: After setting up communications, M available sub-channels are found out from N sub-channel based on the channel state information after the receiving end estimates the channel state information available and forbidden sub-channels are labeled separately to form the sub-channel label information to be fed back to the sending end by the back channel. The sending end alters signal spectrums according to said received labeled information and transmits signals with the available sub-channels. The receiving end transforms the signals to frequency domain then to select signals on the available sub-channel then to balance the selected signals to be transformed to the time domain for judgment to get the transmitted date.

Description

(1) Technical field

[0001] The invention relates to a broadband digital communication transmission method. The invention belongs to the technical field of broadband wireless communication. (2) Background technology

[0002] Communication technology has developed rapidly in recent decades, especially since the 1990s, and has had a profound impact on people's daily life and the development of the national economy. In the future, communication technology is developing towards broadband and high speed, so many broadband digital transmission technologies have received extensive attention. Orthogonal Frequency Division Multiplexing (hereinafter referred to as OFDM: Orthogonal Frequency Division Multiplexing) and frequency-domain -FDE: Single Carrier with Frequency Domain Equalization) are two broadband digital transmission technologies that people value. Become a supporting technology, such as: IEEE802.11a in Wireless Local Area Network (WLAN: Wireless Local Area Network), Hiper...
