摘要： Methods and apparatuses for determining scrambling codes for minimizing co-channel interference in a communication system. A method in accordance with the present invention comprises defining at least one initial default sequence, generating a scrambling code, scrambling a signal using the generated scrambling code, comparing the scrambled signal with all other scrambled signals meeting a specified criterion, and saving the scrambling code word if the comparison determines that the signal scrambled with the scrambling code also meets the specified criterion. The scrambling codes can be compared with each other for cross-correlation purposes to determine whether they meet the specified criterion based on laboratory testing.

摘要： A simplified scrambling scheme that unifies all signals of a satellite broadcasting system, including frame header (404), frame body (402) and pilot symbols (408) with a common reference phase. This results in the simplification and increased flexibility of the receiver front-end design without affecting the overall system performance. In many current communications systems with frame headers and pilot symbols, the phases of frame headers and pilot syrnbols are not designed to be aligned with any constellation points of the modulated data from the frame body. This scrambling scheme takes into account possible impact due to irregular phase changes between frame headers/pilot symbols and modulated data.
摘要翻译： 一种简化的加扰方案，其将具有公共参考相位的卫星广播系统的所有信号（包括帧头部（404）），帧体（402）和导频符号（408）统一起来。 这导致了接收机前端设计的简化和增加的灵活性，而不会影响整个系统的性能。 在具有帧头和导频符号的许多当前通信系统中，帧头和导频符号的相位不被设计为与来自帧体的调制数据的任何星座点对准。 该加扰方案考虑到由帧头/导频符号和调制数据之间的不规则相位变化引起的可能的影响。
