64b/66b's design goals are clock recovery, stream alignment, DC balance, transition density and run length. 8b/10b encoding guarantees strict bounds on DC balance, transition density and run length, whereas 64b/66b provides statistical bounds on these properties. Most clock recovery circuits designed for SONET OC-192 and 64b/66b are specified to tolerate an 80-bit run length. Such a run cannot occur in 64b/66b because transitions are guaranteed at 66-b… Webscrambling code = spreading factor Number of codes Uplink: 10 ms 38400 chips or 66.7 μs = 256 chips Downlink: 10 ms = 38400 chips 4-256 chips (1.0-66.7 μs) Downlink also 512 … six sigma global institute black beltWeb15.6 Spreading and Scrambling in UMTS In a WCDMA system, isolation between users in the downlink is accomplished through the combination of user-specific channelization codes and cell-specific scrambling codes.

A scrambler (or randomizer) can be either: 1. An algorithm that converts an input string into a seemingly random output string of the same length (e.g., by pseudo-randomly selecting bits to invert), thus avoiding long sequences of bits of the same value; in this context, a randomizer is also referred to as a scrambler. 2. An analog or digital source of unpredictable (i.e., high entropy), unbiased, and usually independent (i.e., rando…
