We propose and experimentally demonstrate a 60-GHz ultra-high throughput (VHT) wireless over fiber multicast system. A novel 16-QAM-OFDM hierarchical modulation is implemented and 2.5-dB performance improvement is achieved comparing with conventional I-Q modulation.
We propose two new techniques to mitigate the "edge effect" of the traditional Discrete Fourier Transform (DFT)based channel estimator for OFDM systems with Null subcarriers. Both techniques try to reduce the "edge effect" by generating virtual pilots (VP) in the receiver to fill the missing pilots in the Null spectrum. In the first technique, VPs are generated such that the channel...
