摘要： The invention dispenses with calibration of the optical frequency of the light source and permits the use of many codes without increasing the transmission bandwidth used. Let the optical frequency width of the light source be represented by FSR and the code length of every code be represented by FSR, the codes are made to be orthogonal to each other. The optical intensity-frequency characteristic of an n-th optical code signal is set to Cn(f)=(1+cos(2πsf/FSR+rπ/2))/2 (where s is an integer in the range from 1 to maximum number of codes/2, and r=0 or 1) to provide orthogonality between the optical code signals. Alternatively, optical frequency chips are sequentially assigned to chip sequences forming the optical code signals, the optical frequency of each chip “1” is output, and a filter is provided with an optical filtering characteristic of a concatenated code which is a repeated continuation of, for example a second-order Hadamard code word (0101) or (0011), and light emitted from the light source is passed through the filter to form the optical code signal. An encoding optical frequency region 31 and a decoding optical frequency region 32 are so chosen as to cover a range of drift of the source frequency. In FIG. 13, ΔF1 and ΔF2 indicate drifts of the source frequency.

摘要： A system for bidirectional communication of digital data between a central unit and a remote unit wherein the need for tracking loops in the central unit has been eliminated. The central unit transmitter generates a master carrier and a master clock signal which are used to transmit downstream data to the remote units. The remote units recover the master carrier and master clock and synchronize local oscillators in each remote unit to these master carrier and master clock signals to generate reference carrier and clock signals for use by the remote unit receiver. These reference carrier and clock signals are also used by the remote unit transmitters to transmit upstream data to the central unit. The central unit receiver detects the phase difference between the reference carrier and clock signals from the remote units periodically and adjusts the phase of the master carrier and master clock signals for use by the central unit receiver to receive the upstream data.

摘要： An orthogonal pilot tone servo controller provides a servo control loop for each tap in a delay line processor where each servo acquires its independence from the other tap's servos utilizing an orthogonal code set modulated on top of the existing tap values. The orthogonal codes are attenuated in amplitude such that the code sets are transparent to the processed signals of interest, but the code's length enables each tap's servo controller to independently recover the tap's state from the aggregate of signals and codes through processing gain realized in each loop's recovery circuit. A plurality of taps can be thus be servo controlled simultaneously, providing for extremely wide bandwidth processes which can be performed accurately with digital controls.
