BMS transmitters feature superior COFDM performance that is adequate to support split channel operation in a 12MHz channel (see BMS white paper). The ODU provides signals to control an antenna relay and feed polarity. Additional contact closures are also provided for user specific applications. - Page 11 (duplicate equipment setups). The system can be controlled remotely via an RS232 control port as well; consult BMS for the protocol specification for this port.

Page 44: Coded Orthogonal Frequency Division Multiplex (Cofdm) Modulation
Modulation is the process of varying a carrier signal in order to use that signal to convey information. Quadrature amplitude modulation (QAM) is a modulation scheme which conveys data by changing (modulating) the amplitude and phase of two carrier waves. BMS uses the forms QPSK, 16QAM, and 64QAM. - Page 45 Code Rate The code rate represents the amount of Forward Error Correction (FEC) used for each active symbol. FEC is a method of obtaining error control in data transmission. A code rate of ½ means that for two bits of information received, 1 bit is the real data.
