Single-carrier communication using decision-feedback equalization for multiple antennas
There is an ongoing discussion in the broadband wireless world between OFDM and single-carrier. Single-carrier allows for more relaxed front-end requirements. OFDM, on the other hand, can yield better performance at low complexity. Recently, a new single-carrier scheme with frequency domain equaliza...

Summary: | There is an ongoing discussion in the broadband wireless world between OFDM and single-carrier. Single-carrier allows for more relaxed front-end requirements. OFDM, on the other hand, can yield better performance at low complexity. Recently, a new single-carrier scheme with frequency domain equalization and decision-feedback has been proposed for a SISO channel. This single-carrier scheme can reach the OFDM performance. We extend this new scheme for multiple antennas and multiple users. We show that this multi-user scheme with decision-feedback has a 3 dB gain over conventional linear single-carrier multi-user schemes and still maintains a low complexity. We illustrate that our scheme is equivalent with the generalized decision-feedback equalizer, but has a lower complexity. |
