Description: 通过MATLAB软件；通过仿真得出性能曲线；从而比较bpsk的性能-The bit-error rate (BER) of binary phase-shift keying
in Rayleigh fading, using the Alamouti transmission scheme and
receiver selection diversity in the presence of channel-estimation
error, is studied. Closed-form expressions for the BER of log-likelihood
ratio selection, signal-to-noise ratio (SNR) selection, switchand-
stay combining selection, and maximum ratio combining are
derived in terms of the SNR and the cross-correlation coefficient
of the channel gain and its corrupted estimate. Two new selection
schemes, space–time sum-of-squares combining selection diversity
and space–time sum-of-magnitudes selection diversity, are
proposed and proven to provide almost the same performance as
SNR selection, but with much simpler implementations. The effects

Frequency domain channel estimation is based on interpolation, polynomial generalized linear model (or least squares) and the Wiener filter (or linear minimum mean square error method) method. Time domain channel estimation is done using linear interpolation. We are by measuring the scattering model based on Clark and Rayleigh fading channels with QPSK modulation bit error rate of crude, has compared the results of all these programs. Platform: |

Description: — Performance comparison of multiuser OFDM-TDMA and
OFDMA systems by considering physical and link cross-layer behavior
is conducted in this work. We provide a new framework for performance
evaluation that centers on “ scheduling” with several different
subcarrier/bit allocation schemes. The performance metrics include: the
bit rate, the bit error rate (BER), packet throughput and delay. The
instantaneous channel conditions of users are assumed to be available
at the base station, which can be achieved by channel estimation at the
mobile terminal (MT), and then fed back to the base station through
a control channel. To perform the link layer comparison, we model the
Rayleigh fading channel with a nite-state Markov chain, and adopt the
M/G/1 queueing model as the analytical tool. Computer simulation is
performed to verify conducted analytical results-— Performance comparison of multiuser OFDM-TDMA and
