简介:
The process involves generating Walsh codes, subsequently producing data specifically tailored for User1. Furthermore, it encompasses spreading and Inverse Fast Fourier Transform (IFFT) operations designed for User1, alongside the addition of a cyclic prefix for that user. Following this, data generation occurs for User2, accompanied by spreading and IFFT processing specific to User2, and the inclusion of a cyclic prefix intended for User2. Finally, the system incorporates data preparation for overall transmission across all users, along with the introduction of Rayleigh channel characteristics and the addition of additive white Gaussian noise (AWGN) to simulate realistic channel conditions.
