摘要： For ensuring a low cost transport of signals in a radio network, in particular with a high density of radio access points, a method is proposed, where the signals are transported over wires between a base station and radio access points, comprising the steps of:
- determining the useful band of each wire (20);
- associating at least two wires (21);
- filtering the signal into sub-bands (22);
- transporting each sub-band over one or more wires of the associated wires (25);
- at the receiving end rebuilding the signal from the sub-bands (27).
Further proposed are a radio head and a radio controller both adapted to the present method.

摘要： In systems and methods for randomizing data communicated across a digital interface, a PN sequence is applied to a series of shift registers (141). An array of exclusive-or gates (142) is provided to scramble each bit of the current data word using a respective output of one or several of the shift registers. A second pseudonoise sequence is additionally applied in parallel to another array of exclusive-or gates (143). Additional lines are provided to communicate the PN sequences from the transmitting side to the receiver side. Also, corresponding arrays of exclusive-or gates (152, 153) and shift-registers (151) coupled to the PN sequence lines are disposed on the receiver side to recover the original data using the PN sequences.

摘要： A method and a system for compensating for a permutation of L pairs of cable such that the compensation is localized in a trellis decoder of a receiver. The L pairs of cable correspond to L dimensions of a trellis code associated with the trellis decoder. The trellis code includes a plurality of code-subsets. The permutation of the L pairs of cable is determined. A plurality of sets of swap indicators based on the permutation of the L pairs of cable is generated. Each of the sets of swap indicators corresponds to one of the code-subsets. The code-subsets are remapped based on the corresponding sets of swap indicators.

摘要： The present invention is directed to a method of synchronizing data transmission through optical links between first and second communications components. Each of the first and second communications components include an optical laser for transmitting and receiving laser signals to and from each other through the optical links. In an embodiment, the method comprises the steps of: (a) initializing each of the first and second communications components; (b) enabling the optical lasers and optical sensors; (c) exchanging idle packets between the first and second communications components to establish a datapath across the optical links; (d) exchanging test data packets across the datapath established in step (c) to verify connection of the optical links; and (e) upon verification of connection of said optical links in step (d), enabling data flow between said first and second communications components. In particular, this method is applicable to synchronizing data transmission across a parallel optical link comprising a plurality of parallel links.

摘要： A hybrid serial/parallel bus interface method for a user equipment (UE) has a data block demultiplexing device (40). The data block demultiplexing device (40) has an input configured to receive a data block and demultiplexes the data block into a plurality of nibbles (42(2)). For each nibble, a parallel to serial converter (42(i)) converts the nibble into serial data. A line (44) transfers each nibble's serial data. A serial to parallel converter (46i) converts each nibble's serial data to recover that nibble. A data block reconstruction device (48) combines the recovered nibbles into the data block.

摘要： In one example embodiment, a high-speed parallel-data communication approach transfers digital data in parallel from a first module to a second module over a communication channel including a plurality of parallel data-carrying lines and a clock path. The parallel bus lines are arranged in a plurality of groups, each of the groups including a plurality of data-carrying lines and a clock path adapted to carry a clock signal for synchronizing digital data carried from the first module to the second module. The sets of data are concurrently transferred using the groups of lines of the parallel bus, and at the second module and for each group, the transferred digital data is synchronously collected via the clock signal for the group. At the second module, the data collected for each group is aligned. By grouping the bus lines in groups with each group having its own clock domain, skew across clock-domain groups is tolerated and overcome by processing the data and the skew first within each clock domain group, and then between groups.

摘要： A circuit for receiving multiple serial datastreams in parallel is disclosed. A bit clock is recovered from each data stream, there being one data bit for each transition of the clock signal both positive and negative going. The phases of the bit clocks are compared and are adjusted by 180 degrees so that the positive going edges of all occur close to each other. The bits of each stream are assembled into words under the control of a word clock. In one embodiment a common word clock is derived from the set of bit clocks as a whole. In another embodiment each stream is provided with its own word clock which is aligned to positive edges of the respective bit clocks that are close to each other.
