For instance, at time t = T b /2 the cross bilinear product evaluated is given as Figure 2 Time-lag representations of a PSK signal with lag-window width.
By applying the LLAC on the cross bilinear product, the resulting adaptive window resembles the shape of a parallelogram as shown in Figure 3.

The Fourier transform of the time-lag representation to obtain the TFR requires 0.5N (N τ log2 N τ ) multiplications. .
The Fourier transform of the time-lag representation to obtain the TFR requires 0.5N (N τ log2 N τ ) multiplications.
1. Computation of the cross bilinear product to obtain its time-lag representation requires N τ N multiplications.
This section describes the characteristics of the cross bilinear product in the time-lag representation and outlines the derivation of the AW-XWVD.
A box function is used in the representation of the reference signal to keep track of the location of interaction between the signals of interest with the reference signal in the time-lag representation.
Alongside these efforts, a focus remains on enhancing diversity in the research workforce and professoriate, as the representation of women and scientists from underrepresented minority (URM) backgrounds continues to lag their representation in the PhD pool (National Institutes of Health [NIH], 2014a; Rockey, 2014).
It lags in Hispanic representation (18 percent enrolled versus 38 percent statewide) and African-American (4 percent versus 12 percent statewide).
And Hazaras have flooded the security forces, and now are a disproportionate fraction of soldiers, while Pashtun representation continues to lag.
Viewed in this way, the weaker representation of the lag source need not be attributed to a lateral inhibition-like process [11], [38], although such a process is not excluded.
