However, in reality, it is executing the threads in these programs in a consecutive ... continue execution on the same processor. This eliminates the performance problems inherent with funneling applications to processor 0. If you want to delve into the NKS API set, much inf...

... Adaptive clutter rejection in the joint angle-doppler domain can be incorporated into existing radar systems by digitizing the difference channel, or making relatively minor antenna modifications ... idea of cascading SAPS and STAP itself is not new, and the original work can be found in [29], with other names such as “twostep nulling (TSN)” used in [30]. A key issue in applying this i...

... filtering. Because of significant delay spread in the channel, array processing in mobile communications can be greatly leveraged by processing the signals in space and in time (STP) to minimize ... co-channel interference and inter symbol interference while maximizing SNR. See [35] for a review of channel equalization. We begin with the single-user case where we are only interested in...

... points is somewhat unfair in the following sense. In practice, one finds that in most circumstances the SM algorithm does converge, and furthermore that the convergence point is close to the minimum ... error E{e 2 o (n)}. In most adaptive filtering applications, the desired signal, d(n), is available only during a “training phase” in which the filter parameters are adapted. At the co...

Modeling criteria, such as Akaike’s Information Criterion [18] and minimum description length (MDL) [19] could be used in this situation. Choice ... can draw the following two conclusions regarding this quantity: • The misadjustment increases as the step size is increased. • The misadjustment increases as the filter length...
