摘要
In one embodiment the present disclosure provides a controller to control uplink and downlink communications between at least one baseband unit (BBU) and at least one remote radio head (RRH) in a mobile fronthaul (MFH) network, the controller includes pseudorandom seed generating circuitry to initialize a pseudorandom seeding in the at least one BBU and at least one RRH and to cause the at least one BBU and at least one RRH to generate a pair of matching pseudorandom bit sequences (PRBS), the matching PRBS to enable the at least one BBU and at least one RRH to synchronize communications therebetween; wavelength and route assignment circuitry to select a wavelength and to select a route, through the MFH network, to enable the at least one BBU and at least one RRH to communicate using the selected wavelength and route; error code and modulation format selection circuitry to select an error correction code and a modulation format for communications between the at least one BBU and at least one RRH; transmission configuration circuitry to encode one or more parameters of a physical layer in the MFH network into the PRBS; and bit error rate monitoring circuitry to monitor a data stream between the at least one BBU and at least one RRH to determine if a bit error rate has changed for each frame of the data stream.
