Abstract

This invention provides a bit loading method in a frequency selection single carrier blocking transmission system including the following steps: 1, The receive end gets balanced noise power according to the selected available sub-channel numbers M and their amplitude gain to get balanced S / N ratio in terms of the received S / N ratio and the balance way, 2,the receive end determines the applied different linear modulation ways, the data describing different linear modulation ways are called information of modulation way and sent to the send end via a feed back channel, 3, which images symbols and sends signals, 4, the receive end demodulates the signals and judges them.

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. The future communication technology is developing in the direction of broadband and high speed, so many broadband digital transmission technologies have received extensive attention, such as Orthogonal Frequency Division Multiplexing (hereinafter referred to as OFDM: Orthogonal Frequency Division Multiplexing) and frequency domain balanced -FDE: Single Carrier with Frequency Domain Equalization) are two broadband digital transmission technologies that are valued by people. They both belong to block transmission technology. At present, OFDM has received far more atte...
