Problems solved by technology

[0013] Through the above analysis, it can be seen that the current symbol interleaving method is only randomly selected according to the ACK / NACK information from the receiving end. The interleaving method cannot directly determine the appropriate symbol interleaving method according to the receiving result, but can only be determined by multiple retransmission experiments with different symbol interleaving methods. Therefore, the current method of symbol interleaving requires multiple retransmissions of data, so Affects system throughput and poor transmission performance

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0033] In the embodiments of the present invention, channel conditions are considered when selecting a symbol interleaving mode. Specifically, the transmitting end acquires channel quality information; the transmitting end uses the acquired channel quality information to select a better symbol interleaving mode, thereby reducing transmission errors and improving system throughput.

[0034] The method for selecting the symbol interleaving mode provided in the embodiment of the present invention and the transmitter for realizing the selection of the symbol interleaving mode are described below only by using a multi-carrier system that does not support error packet retransmission.

[0035] Since the embodiment of the present invention selects the symbol in...

Abstract

The invention discloses a method for selecting symbol interleaving modes. The method comprises the steps that: a transmission end acquires channel quality information and selects a symbol interleaving mode by utilizing the channel quality information. The invention also discloses a device for realizing symbol interleaving mode selection, which comprises an information acquiring module and a symbol interleaving mode selecting module. The invention can improve the throughput.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for selecting a symbol interleaving mode in a multi-carrier system, and a transmitter for realizing symbol interleaving. Background technique [0002] In a communication system, due to the complexity of the channel, such as multipath fading due to reflections from buildings, etc., the level of the received signal varies greatly with time, and communication transmission errors usually occur in bursts The form is concentrated, so at the receiving end, the bit errors will appear in the received signal in a continuous form. In order to avoid information distortion caused by continuous bit errors, interleaving technology is usually used, that is, by changing the transmission order of the signal, the continuous bit errors are dispersed, so that other technologies, such as error correction coding, can be used to correct scattered bit errors, thereby improving Error...
