Microcellular mobile communication system

A micro cellular system for use in a wireless communication system based on a Code Division Multiple Access (CDMA) technology, comprising:

• a micro base station controller (mBSC) ,connected to abase station controller(BSC), for receiving forward link traffic signals from the BSC, performing a spread modulation with respect to the forward link traffic signals, supporting an inter-cell handoff, combining the spread modulated signals, converting the combined signals into analog signals by using a digital modulation scheme and converting the analog signals into forward link hybrid fiber-radio(HFR) cable frequency signals in a forward link, and for receiving reverse link HFR cable frequency signals, extracting carrier signals bearing reverse link traffic signals from the reverse link HFR cable frequency signals, frequency down converting the carrier signals, converting the frequency down converted signals into reverse link digital signals by using a digital demodulation scheme, performing a spread demodulation with respect to the reverse link digital signals to thereby produce reverse link traffic signals and transmitting the reverse link traffic signals to the BSC in a reverse link;
• a plurality of micro base stations, each connected to the mBSC and whole or part of the plurality of the micro base stations being included in a same micro cell, for transferring the HFR cable frequency signals including the forward link and the reverse link HFR cable frequency signals and transmitting/receiving RF (Radio Frequency) signals to/from a multiplicity of mobile stations, wherein each micro base station has one among a laser diode whose optical wavelengths are separated from each other and a light emitting diode;
• and
• a HFR network, connecting the MBSC to the plurality of micro base stations, for converting the forward link HFR cable frequency signals into forward link optical signals, outputting the forward link optical signals via a single optical fiber core connected thereto and distributing the forward link optical signals to each micro base station in the forward link, for combining reverse link optical signals received from each micro base station, the combined reverse link optical signals being transferred via the single fiber core, converting the reverse link optical signals into electrical signals to thereby produce reverse link HFR cable frequency signals and transferring the reverse link HFR cable frequency signals to the mBSC,
• wherein the micro cell is distinguished from other micro cells by its forward link and reverse link HFR cable frequency bands and the number of the frequency bands of each of the forward link and the reverse link HFR cable frequency signals ranges from one to the number of the plurality of the micro base stations.
