Hitless Modulation Changes in Double Capacity Links Using Adaptive Coding Modulation (ACM)

摘要

An outdoor communication unit (ODU) for implementation within a dual channel microwave backhaul system, is provided. The ODU includes an radio frequency (RF) module, having digital capabilities, which is configured to utilize the digital capabilities to perform adaptive adjustments to correct errors in data in a digital domain, a conversion block configured to convert the data between an analog domain and the digital domain, and a processing module configured to adaptively adjust a characteristic of the data and a characteristic of a dual channel wireless link, and to facilitate a transmission of the data over the dual channel wireless link by performing mathematical manipulation techniques. In particular, the characteristic of the data and of the dual channel wireless link are adaptively adjusted, according to a detected condition, using a hitless adaptive coding modulation (ACM) technique to optimize the transmission of the data over the dual channel wireless link
