摘要：
In this paper, we design a complete baseband system of a high data rate packet-type OFDM receiver. For mobility support and channel-gain phase tracking, we propose a simple pilot tone insertion method that not only facilitates low-complexity channel gain tracking but also enables carrier frequency tracking. Besides, an efficient mechanism for packet boundary detection is also provided. In addition to channel gain tracking and packet boundary detection, timing synchronization, coarse frequency offset estimation, and fine frequency offset tracking issues are also discussed and simulated.
