Abstract
This paper analyzes the achievable sum-rate of correlated two-antenna multiple-input multiple-output
(MIMO) uplink channels. Most of previous works have considered the case when a single user has
multiple transmit antennas (i.e. multi-antenna single-user scenario). This paper considers the case when
two-antenna MIMO uplink channels comprise two users with a single transmit antenna (i.e. single-antenna
two-user scenario). The analytic and simulation results show that the achievable sum-rate of correlated
single-antenna two-user MIMO uplink channels highly depends on the angle difference between the
receive correlation coefficients of two users. It is also shown that the achievable sum-rate of correlated
single-antenna two-user MIMO uplink channels is larger than that of correlated two-antenna single-user
MIMO uplink channels and can even be larger than that of independent and identically distributed Rayleigh
two-antenna MIMO uplink channels.
