Abstract: A bit clock signal which contains gaps inserted with one-bit accuracy for frame-clock detection is needed particularly in combined multiplexing and switching devices for digital signals. Having regard to the high accuracy in inserting the gaps, on the one hand, and to the great difference in frequency between the gapped clock and the bit clock, the extraction of the two clock signals from a system-generated normal clock is combined in such a manner that only the phase-locked loop provided for extracting the bit clock signal is synchronised by the normal clock via a frequency divider and a phase discriminator. Having regard to the required high operational reliability, the overall arrangement for generating the clock signals is constructed of two modules of identical configuration, additional synchronism being established between the frequency dividers of both modules which are of particular importance for the operation. <IMAGE>

Abstract: A high speed tape transport system is provided with precise registration means for guide posts of a cassette. A fixture is provided with spaced apart precise annular registation surfaces which are located in the same reference plane. The guide posts each have a precise annular registration surface at one end. A bottom wall of the cassette is supported by the fixture independently of the fixture registration surfaces and includes a portion which is also in the same reference plane. The bottom wall has a pair of spaced apart openings aligned with the fixture registration surfaces. The one end of each guide post is placed through a respective bottom wall opening and with the annular registration surface of each guide post engaging a respective annular registration surface of the fixture, the guide posts are fixed to the bottom wall by an epoxy resin. This sets the distance between certain points on the guide post relative to the reference plane. This also sets the axis of the guide posts precisely perpendicular to the reference plane and precisely parallel to each other. The connection of each guide post to the bottom wall is the sole connection of the guide posts to the cassette so the settings will not be disturbed by the engagement or tolerances of the guide posts with other members. The surfaces of each spindle and the axis of each spindle are also set relative to the same reference plane. 
     A tape drive is provided which has spaced apart precise annular registration and support surfaces which are in the same plane which replicates the spaced apart precise annular registation surfaces and the reference plane of the fixture. The drive also has a third registration portion in the same plane which replicates the portion in the reference plane on the fixture supporting the bottom wall. When the cassette is placed onto the drive, the annular registration surface of each guide post is the only part of the cassette that engages a respective one of the annular registration and support surfaces of the drive and the same portion of the bottom wall, which engaged the portion of the fixture in the reference plane, engages the third registration portion of the drive. In this manner, the distances to certain points on the guide posts from the reference plane on the drive remain the same as set and the axes of the guide posts and spindles are precisely parallel to each other and all relative points on the spindle and the guide posts remain precisely the same.

Abstract: A DS-CDMA system comprises at least one transmitter and at least one receiver operating on a dedicated signal channel which is used by other DS-CDMA operators in a non-synchronous way. A receiver for use in such a DS-CDMA system includes a data aided multiuser interference canceller (38) comprising a feedforward filter (48) connected to a subtracting stage (50). A decision stage (52) is connected to an output of the subtracting stage (50). Decisions from the decision stage (52) are stored in a memory which also stores preliminary decisions made on the signal applied to the feedforward filter (48) by a simple receiver (46). These decisions are applied to a feedback filter (58) the output of which is connected to the subtracting stage (50) thereby removing the effects of pre-cursive and post-cursive interference. The input to, and output from, the decision stage 52 are compared and the difference is used for adjusting the tap weights of the feedforward and feedback filters (48,58). In the case of a single input, single output, the feedforward filter (48) comprises a fractionally spaced equalizer which despreads and filters the DS-CDMA signal. In the case of multiple input, multiple output, the received signal is despread in a bank of code matched filters and the output is applied to the canceller (38) in which the feedforward filter (48) comprises a linear synchronous equalizer.
