详 情 说 明

The following is a description of the OFDM channel characteristics and the Channel Transmission Simulator. The Channel Transmission Simulator has several inputs including noise variance, number of transmitting antennas, number of receiving antennas, a vector of complex input symbols (which is a matrix for MIMO where each column represents the value of the antenna outputs at a single time instance), frequency selective channel represented in block-Toeplitz form for MIMO transmission, and the number of symbols transmitted in the OFDM frame. The simulator's outputs include a vector of channel outputs (which is a matrix for MIMO, just like the input symbol matrix). To create a noise vector sequence, each row represents a different antenna and each column represents a different time index. It is important to note that the noise is spatially and temporally white.

In summary, the Channel Transmission Simulator is a tool that allows users to analyze and understand the characteristics of the OFDM channel. Its inputs include various parameters such as the number of antennas and the number of symbols transmitted, while its outputs include a vector of channel outputs. By creating a noise vector sequence, users can gain a better understanding of how noise affects the transmission of signals across different antennas and at different time intervals.
