Abstract: A direct sequence spread spectrum receiver samples an incoming signal at a low non-integer sample rate relative to the input data rate. The sample rate is an integer rate relative to a defined data segment. As multiple segments are sampled, the non-integer sample rate causes bit/chip samples to process relative to the incoming data. Because the sample rate is an integer relative to a data segment, the samples are substantially stationary relative to each segment. Such a method is useful in global positioning satellite (GPS) signal processing wherein the time to first fix is minimized by having to correlate fewer sample points in the acquisition process.

Abstract: A circular MAP decoder for error-correcting trellis codes that employ tail biting produces soft-decision outputs provides an estimate of the probabilities of the states in the first stage of the trellis, which probabilities replace the a priori knowledge of the starting state in a conventional MAP decoder. The circular MAP decoder provides the initial state probability distribution in either of two ways. The first involves a solution to an eigenvalue problem for which the resulting eigenvector is the desired initial state probability distribution; with knowledge of the starting state, the circular MAP decoder performs the rest of the decoding according to the MAP decoding algorithm. The second is based on arecursion for which the iterations converge to a starting state distribution. After sufficient iterations, a state on the circular sequence of states is known with high probability, and the circular MAP decoder performs the rest of the decoding according to the MAP decoding algorithm.

Abstract: A 3DFT MRA dynamic study is performed using a contrast agent to enhance image contrast. A monitor pulse sequence is performed at a high temporal rate to monitor the magnitude of the NMR signal produced in a monitor region after the contrast agent is injected into the patient. When the monitor signal reaches a threshold value, the patient is signaled and the 3DFT image data set is acquired.
