Absolute phase in mobile channels

Absolute phase in mobile channels

Mobile channels are often modeled using a well-defined Rice process. The statistics of its wrapped phase (i.e., phase values in [−π, π)), such as the mean, variance, and probability density function (pdf), are known. The absolute phase is the accumulated phase change over an observation interval. It can be calculated from the wrapped phase but contains more information. Its applications include...

CAPE: combinatorial absolute phase estimation.

An absolute phase estimation algorithm for interferometric applications is introduced. The approach is Bayesian. Besides coping with the 2pi-periodic sinusoidal nonlinearity in the observations, the proposed methodology assumes a first-order Markov random field prior and a maximum a posteriori probability (MAP) viewpoint. For computing the MAP solution, we provide a combinatorial suboptimal alg...

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

Modeling of MIMO Mobile-to-Mobile Channels

Novel phase-coding method for absolute phase retrieval.

This Letter presents a novel absolute phase recovery technique with phase coding. Unlike the conventional gray-coding method, the codeword is embedded into the phase and then used to determine the fringe order for absolute phase retrieval. This technique is robust because it uses phase instead of intensity to determine codewords, and it could achieve a faster measurement speed, since three addi...
