Transcoder architecture for land mobile radio systems

摘要

A transcoder architecture and method for transcoding in land mobile radio (LMR) systems are provided. The LMR system (20) includes a first communication site configured to communicate using a first LMR communication protocol and a second communication site configured to communicate using a second LMR communication protocol. The LMR system further includes a transcoder (28) configured to receive LMR content from the first communication site communicated using the first LMR communication protocol and digitally convert the LMR content to the second LMR communication protocol to be communicated to the second communication site. The transcoder (28) is configured to digitally translate a plurality of transcoder speech vectors from a first vocoder type to a second vocoder type without any devocoding.
