Mathews, V. John | Pilot embedding for channel estimation and tracking in OFDM systems | Abstract-We consider the problem of channel estimation and tracking in OFDM systems and explore the idea of adding pilot symbols to the data symbols as a means to conserve bandwidth. The term pilot embedding (PE) is used to refer to this scheme. Compared to the pilot insertion (PI) scheme, i.e., the... | 2004 | |
