| 发明名称 | Blind equalization of dual subcarrier OFDM signals | ||
| 摘要 | A dual-polarization, 2-subcarriers code orthogonal, orthogonal frequency division multiplexed signal carrying information bits is transmitted in an optical communication network without transmitting a corresponding pilot tone or training sequence. A receiver receives the transmitted signal and recovers information bits using a blind equalization technique and by equalizing the 2-subcarriers OFDM signal as a 49-QAM signal in time domain with a CMMA (constant multi modulus algorithm) equalization method. | ||

| 主权项 | 1. A method for recovering data from a two-subcarrier orthogonal frequency division multiplexed (OFDM) signal in which each subcarrier is modulated using a 16 Quadrature Amplitude Modulation (QAM) constellation, comprising: receiving the two-subcarrier OFDM signal; converting the two-subcarrier OFDM signal into a time domain 49 QAM signal; and performing blind equalization of the time domain 49 QAM signal using a cascaded multi-modulus algorithm (CMMA) to recover the data. | ||
