System and method for routing and up-converting narrowband channels

摘要

A device that may include a router and may also include narrowband generators arranged to generate samples of narrowband channels, a digital up converter (DUC). The DUC may include multiple DUC inputs. Different DUC inputs are associated with different frequency ranges. The router may include multiple router inputs, multiple router outputs and a routing circuit. The multiple router outputs are coupled to the multiple DUC inputs. The multiple router inputs are coupled to the narrowband generators. The routing circuit may include a re-sequencing memory module that is arranged to receive the samples of narrowband channels from the narrowband generator according to an input order and to output the samples of the narrowband channels to the multiple router outputs according to an output order that is responsive to an allocation of frequencies to the samples of the narrowband channels.
