Abstract
Single-Carrier Frequency Division Multiple Access
(SC-FDMA) has been selected as the uplink transmission scheme
in the 3GPP Long Term Evolution standard. SC-FDMA is a form
of Single-Carrier Frequency Domain Equalization (SC-FDE) with
a flexibility in resource allocation, thus it has reduced sensitivity
to phase noise and a lower Peak-to-Average Power Ratio (PAPR)
compared to Orthogonal Frequency Division Multiple Access.
This, consequently, makes it more attractive for low cost devices
with limited transmit power. In this paper we propose an
optimum power allocation scheme for SC-FDMA transmission
considering Frequency-Domain Linear Equalization (FD-LE).
We derive the optimum power allocation for the SC-FDMA
transmission for both a Zero-Forcing (ZF) and a Minimum
Mean-Square Error (MMSE) receiver in order to maximize the
achievable rate subject to a constant transmit power. Results
show that the optimum power allocation for the MMSE FD-LE
results in greater improvement in the achievable transmission
rate compared to ZF FD-LE.
