A new combined equalization/synchronization technique, known as SC-PMC (self-convoluting partial mass center), for use in partial response systems is presented. The work is significant as the new technique utilizes a single tap delay line LMS (Least Mean Square) filter for performing the task of equalization and synchronization for the partial response transceiver. Conventional partial response...

Traditionally, room response equalization is performed to improve sound quality at a given listener in applications ranging from automobile, home-theater, movie theater, multimedia education in classrooms. However, room responses vary with source and listener positions. Hence, in a multiple listener environment, equalization may be performed through spatial averaging of magnitude responses at l...

In this paper, we investigate the performance of two different receiver proposals using space-time block coding for frequency selective fading channels. The first one, called equalization pos-combining with channel estimation receiver, is based on the time-reverse space-time block coding proposed by Lindskog and Paulraj and it performs channel-estimation, linear combination and equalization. Th...

Recently, multi-carrier code division multiple access (MC-CDMA) has been attracting much attention for the broadband wireless access in the next generation mobile communications systems. In the case of uplink transmissions, the orthogonality property among users’ signals is lost since each user’s signal goes through different fading channel and hence, multi-access interference (MAI) is produced...

Contrast enhancement is an important factor in the image preprocessing step. One of the widely accepted contrast enhancement method is the histogram equalization. Although histogram equalization achieves comparatively better performance on almost all types of image, global histogram equalization sometimes produces excessive visual deterioration. A new extension of bi-histogram equalization call...

Histogram Equalization (HE) has been an essential addition to the Image Enhancement world. Enhancement techniques like Classical Histogram Equalization(CHE),Adaptive Histogram Equalization (AHE), Bi-Histogram Equalization (BHE) and Recursive Mean Separate Histogram Equalization (RMSHE) methods enhance contrast, brightness is not well preserved, which gives an unpleasant look to the final image ...

Abstract In multi carrier code division multiple access (MC-CDMA), since signals transmitted from different users go through different frequency-selective fading channels, the use of frequency-domain equalization at a receiver can only partially restore the orthogonality property among different users’ signals, resulting in the degraded bit error ratio (BER) performance due to large multi-acces...
