“…Second, the effective noise termη (i.e.,η or ξ) is circularly symmetric. Under those assumptions, we can express the BER as a sum of components of error probability (CEPs) that depend on the effective noise CDF [13], that is,…”

Single Carrier Frequency Division Multiple Access (SC-FDMA) is nowadays a promising technology for uplink transmission in 4G mobile communications systems. That is mostly due to its favorable envelope characteristics, its low PAPR and to the fact its performance is similar to that achieved with Orthogonal Frequency Domain Multiple Access (OFDMA). We present our analysis of the BER for a SC-FDMA transmission over a Rayleigh fading channel for ideal linear frequency-domain equalization. Expressions for the BER under the assumption of independence among allocated sub-carriers are derived and verified through simulations.

“…This is efficiently achieved by using a set of overlapped orthogonal signals to partition the channel. A transceiver can be realized using a number of coherent QAM modems which are equally spaced in the frequency domain and which can be implemented using the IDFT on the transmitter end and the DFT on the receiving end [6,7]. Due to the fact that the intercarrier spacing in OFDM is relatively small, OFDM transceivers are somewhat more sensitive to phase noise by comparison to single carrier transceivers.…”

“…Since the mathematical formulation of multiuser spread-spectrum is very close to that of MIMO communications (see [18] for an overview of this analogy), MIMO linear precoders can be derived along similar techniques. Significant research efforts were then devoted to the analysis of the impact of imperfect channel estimation on such systems, with several authors proposing closed-formulas for BER evaluation in both SISO and MIMO systems affected by channel estimation errors [19][20][21][22].…”

Time reversal (TR) is an effective solution in both single user and multiuser communications for moving complexity from the receiver to the transmitter, in comparison to traditional postfiltering based on Rake receivers. Imperfect channel estimation may, however, affect pre-versus postfiltering schemes in a different way; this paper analyzes the robustness of time reversal versus AllRake (AR) transceivers, in multiple access communications, with respect to channel estimation errors. Two performance indicators are adopted in the analysis: symbol error probability and spectral efficiency. Analytic expressions for both indicators are derived and used as the basis for simulation-based performance evaluation. Results show that while TR leads to slight performance advantage over AR when channel estimation is accurate, its performance is severely degraded by large channel estimation errors, indicating a clear advantage for AR receivers in this case, in particular when extremely short impulsive waveforms are adopted. Results however also show a stronger non-Gaussianity of interference in the TR case suggesting that the adoption of a receiver structure adapted to non-Gaussian interference might tilt the balance towards TR.
