2. Performance Analysis of the Uplink of Multi-antenna Systems Operating in Aging Channels
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In wireless communications, employing pilot symbols enables to estimate the state of the wireless channel at the expense of decreasing the number of symbols available for transmitting data. Addressing this trade-off is particularly challenging when the channel changes rapidly over time, since channel estimates become obsolete over short transmission periods. READ MORE
