Description: 一篇非常实用的无线通信方向的文献,是关于cdma系统中doa估计的经典-The use of antenna arrays in wireless communications
makes it possible to estimate the directions of arrival (DOAs)
of impinging waveforms. The latter can be exploited to enhance
channel estimation accuracy or as an input for advanced mobile
positioning systems. In this paper, we consider the uplink of a
multicarrier code-division multiple-access (MC-CDMA) network
in which the base station is endowed with multiple receiving antennas
arranged in a uniform linear array. Transmission takes place
over a multipath channel, and the goal is the joint estimation of
the channel responses and DOAs of the uplink signals. In doing so,
we follow a maximum-likelihood (ML) approach and assume that
users transmit orthogonal training sequences to facilitate the task
of separating the signals. This way, all unknown parameters are
estimated independently of each other with affordable complexity.
Theoretical analysis and computer simulations are used to assess
the performance of the propose Platform: |

Description: Signal identification represents the task of a receiver
to identify the signal type and its parameters, with applications
to both military and commercial communications. In this paper,
we investigate the identification of spatial multiplexing (SM) and
Alamouti (AL) space-time block code (STBC) with single carrier
frequency division multiple access (SC-FDMA) signals, when
the receiver is equipped with a single antenna. We develop a
discriminating feature based on a fourth-order statistic of the
received signal, as well as a constant false alarm rate decision
criterion which relies on the statistical properties of the feature
estimate. Furthermore, we present the theoretical performance
analysis of the proposed identification algorithm. The algorithm
does not require channel or noise power estimation, modulation
classification, and block synchronization. Simulation results show
the validity of the proposed algorithm, as well as a very good
agreement with the theoretical analysis. Platform: |
