发明名称 Method and apparatus for performing constellation scrambling in a multimedia home network
摘要 Systems and methods are provided that allow multiple transmitting network devices to transmit under an orthogonal frequency divisional multiple access (OFDMA) mode to a receiving network device. The multiple transmitting network devices may be configured to perform constellation scrambling on the symbols they will be transmitting using a predetermined scrambling sequence. They may be further configured to synchronize their use of the sequence, for example, by advancing the sequence for each available subcarrier, such that the receiving device may view the payload as if it were sent by a single transmitter. Accordingly, these multiple transmissions may be descrambled using only one instance of a sequence generator.
