The use of moment generating function method, Rayleigh fading channel is derived using the relevant combination of SC/MRC antenna diversity and coherent detection of M-ary phase shift keying (MPSK), M M-ary quadrature amplitude modulation (MQAM), M-band pulse amplitude modulation (MPAM), such as several M-band digital modulation modes of expression of symbol error rate of accuracy. The numerical results clarify the relevance and structure of antenna arrays using combinations of SC/MRC antenna diversity of several M-band digital modulation of the average symbol error rate performance.

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

Description: This thesis presents simulation data on array operation in wideband communication systems.
It is shown that array structures with closer inter-element spacing outperform structures with
much larger inter-element spacing. It is also shown that circular structures outperform linear
structures. This performance di erence between the classi cations of arrays is due largely
to the circular array s ability to handle high levels of interference. Even though a diversity
combining scheme (MRC) was used in the simulator, the arrays provided interference rejection
capabilities due to the closely spaced antenna elements. Platform: |
