TechOps Request for Proposal Chapter D – Contract Documents, Exhibits, or Attachments RFP No. HSHQDC-11-R-00019 Attachment 5 – Acronyms and Abbreviations

COFDM systems transmit data through the use of multiple carriers within a main signal with each carrier being modulated in one of several ways. The loss of one or more carriers may have little or no impact on the video received. The systems typically employ Forward Error Correction (FEC) coding, further increasing signal reliability.
