A new method of broadband expansion based on frequency division deconvolution and its application in fine reservoir description

CS is a very new method that is being evaluated for many applications, in which signals are sparse in some basis/dictionary, e.g. the radar range profile. In this article, we have formulated the range processing with CS and introduced fair comparisons between matched filter and CS with chirps and OFDM signals. Two relevant features have been inspected: waveform bandwidth and measurement matrix.

Signal Comparison

A new method of amplitude division multiplexing (ADMA) is proposed, where a single channel can be used to transmit multiple digital signals simultaneously using the concept of prime number factorization. This method contrasts with the currently used methods such as frequency-division multiple access (FDMA), in whichthe total bandwidth available in a channel is divided into a series of non-overlapping frequency bands, each ofwhich is used to carry a separate signal. Comparison of the proposed method with a popular PAM technique-2B1Q method is made. Distinct advantages of the proposed method and a few applications arepresented.

Specific Orientation

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.
