Problems solved by technology

As such, a single channel that experiences poor communication channels usually limits the overall transfer rate of multiple channels
For applications that manipulate communication-related data, the transfer rate will be slowed down, and the user will also experience the slowed down transfer rate

Embodiment Construction

[0022] Disclosed embodiments are illustrated along with illustrations, but in some cases, possible embodiments are not shown in the drawings. Where possible, the same reference numbers in the drawings represent the same or similar parts. As used herein, references to "data," "content," "information" and similar terms are used interchangeably to refer to data that may be transmitted, received and / or stored in accordance with the disclosed embodiments.

[0023] As mentioned above, a multiple-input multiple-output (MIMO) technology is applied to multiple antennas at the transmitter and receiver to simultaneously transmit multiple independent data streams to increase the transmission rate. The technology based on the above principles is adopted in the fourth generation wireless communication standard combined with the MIMO mode detailed in the IEEE802.16e standard. Regardless of the specific technology, the MIMO transmission structure is based on a single codeword (SCW) structure...

Abstract

This invention provides different data transmitting methods and devices thereof based on signal priority valve and channel reliability. An demonstrating method of this invention includes: coding multiple bits into coding bits with multiple system bits and multiple parity bits corresponding to each other, for the purpose of transmitting the data, the bits are coding through multiple channels of a communication system with multiple channels, where, the communication system with multiple channels includes a high reliability channel and a lower reliability channel. Said demonstrating method of this invention also includes: assigning system bits to different bits locations corresponding to first series current in channel with high reliability, assigning system bits to different bits locations corresponding to high signal priority valve in second series current in channel with low reliability, and assigning parity bits to the bits locations in second series current. This invention also provides similar or related methods and related devices for assigning system bits and parity bits to corresponding each bits locations in channels with high and low reliability.

Description

technical field [0001] Related to a data transmission, it relates to a data processing for data transmission in a multi-channel communication system. Background technique [0002] A multi-channel communication system is a wireless communication system capable of transmitting information (such as audio and data) between a transmitting end and a receiving end, wherein each of the transmitting end and the receiving end may have at least one transmitting end antenna and one receiving end antenna . For example, the multi-channel communication system may include a multiple-input multiple-output (MIMO) communication system, an Orthogonal Frequency Division Multiplexing (OFDM) system and / or a system based on Orthogonal frequency division multitasking multiple input multiple output system. A MIMO system uses multiple transmitter antennas and multiple receiver antennas to form multiple spatial subchannels in a spatial diversity manner, wherein each subchannel can be used to transmit...
