Embodiment Construction

[0021] The main scope of the present invention is to provide a method and a communication system for receiving a transmission data using an adaptive code rate (Adaptive code rate), and in particular, the method and the communication system are especially suitable for a wireless network middle.

[0022] A preferred embodiment according to the present invention is a method for receiving data over a wireless network using an adaptive coding rate. Please refer to FIG. 1, which shows a flowchart of the data receiving method.

[0023] The method first executes step S20, encoding the same part of the transmission data through the first attenuation matrix and then transmitting through the channel. Step S21 represents receiving the first data packet by the first receiver (Receiver), step S22 represents receiving the second data packet by the second receiver, the first data packet and the second data packet both correspond to the data of the same part of the data . Next, step S23 and...

Abstract

The invention provides a method for using a wireless network via an adaptive code rate to receive data, which comprises that first, coding and receiving a first data pack and a second data pack relative to one same portion of the data via a first reduction matrix, when the decode results of the first and second data packs are both failed, combining the first and second data packs into a third data pack, decoding the third data pack, to obtain the data, and when the decode result of the third data pack is failed, the data is coded by a second reduction matrix with low coding rate, repeating aforementioned processes until the data is decoded correctly.

Description

technical field [0001] The present invention relates to a method for receiving data using an adaptive code rate, and in particular, the method is especially suitable for a wireless network. Background technique [0002] In a wireless communication system, when radio waves are transmitted in the air, they will be affected by terrain and features, resulting in phenomena such as refraction, diffraction, interference, and multiple path attenuation, resulting in channel instability in the transmission environment. Therefore, how to ensure that data can be received correctly through an appropriate error control mechanism has become an important issue in the development of wireless networks. [0003] Antenna diversity technology commonly used in wireless networks today is used to increase the probability of data being received correctly. The basic concept of antenna diversity is that the receiving end can receive several different versions of the packet sent by the transmitting en...
