Description: Cross – Correlation of the Two FSK Signals.
FREQUENCY SHIFT KEYING - ERROR PROBABILITY:
The Probability of error of an FSK system depends on the separation of “distance” d, between two (or more) signals
The probability of error is minimum when the distance of separation is maximum i.e larger the d, smaller is the P.E.
The distance d is given by:
d = (1 - ) / 2
where
= (1 / E) 0 T s0(t) s1(t) dt.
The integral is the cross-correlation function over the period 0 to T. is restricted to values between +1 and –1.

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: we investigate the detection of multi-path signal propagation in a Time Difference of Arrival (TDOA) localization scenario. Usually, TDOA measurements are obtained by determining the absolute maximum of the cross correlation function of signals recorded at different sensor nodes in a sensor network. Multipath signal propagation causes multiple peaks in the cross correlation function which lead to erroneous emitter localization. We use hypotheses of possible multipath signal propagation calculated from the autocorrelation functions to identify the line of sight (LOS) peak in the cross correlation function of a sensor pair.
