摘要： A high frequency signal is down-converted into an intermediate frequency signal, transmitted over a limited bandwidth medium from a master unit to a remote unit and up-converted back into its original high frequency at the remote unit. The up-conversion is aided by reconstruction of a reference signal embedded at the master unit as a carrier for a management signal which is transmitted to the remote unit through the same limited bandwidth medium together with the intermediate frequency signal. The reference signal is reconstructed using a phase locked loop which includes a charge pump and is kept stable during intervals between bits and messages by a charge pump shutter.

摘要： A system and method for ensuring proper synchronization of a plurality of frequency sources used in reception diversity-based radio reception. The frequency sources are concatenated in a synchronization loop, through which one frequency source having a high performance oscillator is configured as a master source. Through its oscillator, the master provides an internal synchronization signal that synchronizes all other sources, which have lower performance oscillators and are configured as slaves. Upon a failure in the master oscillator or in the synchronization loop, a slave source takes over as an alternative master source and provides its internal oscillator signal as an alternative synchronization signal to all other frequency sources.

摘要： A method and system for supporting M1MO technologies which can require the transport of multiple spatial streams on a traditional Distributed Antenna System (DAS). According to the invention, at one end of the DAS, each spatial stream is shifted in frequency to a pre-assigned band (such as a band at a frequency lower than the native frequency) that does not overlap the band assigned to other spatial streams (or the band of any other services being carried by the DAS). Each of the spatial streams can be combined and transmitted as a combined signal over a common coaxial cable. At the other “end” of the DAS, the different streams are shifted back to their original (overlapping) frequencies but retain their individual “identities” by being radiated through physically separate antenna elements.
