Scrambling coding
WebMar 19, 2024 · Two types of scrambling code planning methods for multi-layer asynchronous 3GPP W-CDMA systems are developed by modifying the PN offset planning … 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…
