Embodiment 1
[0068] Embodiment 1: see figure 1 , a spatio-temporal two-dimensional channel coding method, the specific implementation of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that in the following description, since the detailed description of some known technologies and functions may dilute the content of the present invention, these descriptions will be omitted here.
[0069] Consider a MIMO system with a total of N t root transmit antenna, N r Root receiving antenna, there are S data bits to be sent. First, the transmitter sends pilots, and the receiver performs channel estimation. Assuming that the channel is a flat fading channel, if it is a frequency selective fading channel, it can be converted into a flat fading channel in the frequency domain by using the Orthogonal Frequency Division Multiplexing (OFDM) technology. Since this ...
