Embodiment Construction

[0023] According to the above-mentioned spatial modulation (SM) scheme, one of the N available transmission antennas is selected for transmission, that is,

[0024] bit

[0025] can be encoded according to antenna selection and using a modulation constellation with M signal points, then, log 2 The M bits may be encoded according to modulation constellation symbol selection. In the above expression, Represents keeping the value of x as close to the nearest integer value as possible, since a small fraction of bits cannot be transmitted through the selected antenna (this is useful if two of the transmit antennas are selected). therefore,

[0026] bit

[0027] The total number can be sent to each channel used.

[0028] According to the GSSK scheme mentioned above, K antennas are selected for the information bits to be transmitted, and the remaining N-K antennas do not transmit anything. Through this method, K antennas are selected from N antennas (K>1), which has a vari...

Abstract

The present invention relates to a method for transmission in a wireless communication system and more particularly to a method in a transmitter which comprises a plurality of transmit antennas. An example embodiment according to the invention comprises encoding of signals for transmission and provides for transmission over a selected number of transmit antennas.

Description

technical field [0001] The present invention relates to transmission in a wireless communication system, and more particularly to a method of transmission in a transmitter having multiple transmission antennas. In addition, a set of transmitter devices related to the method will be disclosed. Background technique [0002] If a transmitter has multiple transmission antennas, it can choose among various transmission schemes according to the transmission purpose. Transmission schemes can be divided into two categories according to heuristics, ie in terms of their diversity and their capacity. However, some transmission schemes have both capacity and diversity characteristics. [0003] In order to improve the reliability of the wireless link, the transmission diversity scheme has always been the mainstream in the prior art. Most transmit diversity schemes are usually designed on the basis of maintaining a simple receiver structure, and these schemes generally work well with a...
