This study presents an innovative approach to enhance communication systems on High Altitude Platforms (HAPs). Symbol-Wavelength-Spaced antennas and spread spectrum delay multiplexing are combined to increase system capacity, decrease interference, and improve spectrum efficiency. In order to determine the stability and effectiveness of the system, the study analyzes important performance measures, such as determinant, norm, and condition numbers. To enhance signal quality and reduce multiuser interference, a zero-forcing approach is used. The results demonstrate that antenna spacing at symbol-wavelength intervals provides the best performance, especially in line-of-sight communication situations. With its reliable and effective signal transmission, this architecture raises the bar for HAP-Based networks and offers exciting new developments for wireless communication systems in the future.
