¡¡Simulations of signal detection and channel estimation using independent component analysis were performed on the uplink line.
Table 1 shows the simulation parameters for the uplink.
Focusing on the number of terminals (16), a series length of at least 16 symbols is required to perform channel estimation.
However, by using ICA, the number of symbols in the preamplifier was only 5.
In addition, in ICA, the process of equation (7,8) needs to be repeated.
In this study, the weight matrix was sufficiently converged by iterating 30 times. |
