Time-Domain Least Square Channel Estimation for Polarization-Division-Multiplexed CO-OFDM_OQAM Systems
- 基于OQAM/PDM CO-OFDM系统提出了一种时域的信道估计方法，可以有效提高估计效率。
Signal Space Diversity: A Power- and Bandwidth-Efficient Diversity Technique for the Rayleigh Fading Channel
- The increasing need for high data-rate transmissions over time- or frequency-selective fading channels has drawn attention to modulation schemes with high spectral efficiency such as QAM. With the aim of increasing the “diversity order” of the signal
