Abstract
This article discusses asynchronous techniques with spreading sequences (codes) that are statistically uncorrelated for arbitrarily random starting points. We provide improved codes for the spread-spectrum multiple-access asynchronous techniques. The article provides methods for generating improved codes, as well as estimates of their parameters. We investigate the cross-correlation of codes for arbitrarily random starting points. The comparative analysis shows that with a slight increase in the correlation modulus, we can significantly increase the cardinality of the spreading codes. This useful property can be used in future radio control systems and future smart grids to implement soft capacity, i.e. the base station can increase the subscriber capacity with a slight decrease in the quality of service.
