MAP EQUALIZATION AND DECODING IN WIRELESS MOBILE CODED OFDM
OBJECTIVE
 OFDM suffers extra performance degradation in multi path channels due to ICI
 Bit error rate(BER) increases with this ICI
 To reduce the BER suitable equalizer is needed.
 That equalizer should not limit the advantages of OFDM
OFDM
 Orthogonal Frequency Division Multiplexing (OFDM) is a special form of multi carrier modulation technique which is used to genera ....etc

ABSTRACT
Forward Error Correction techniques are utilized for correction of errors at the receiver end. Convolutional encoding is an FEC technique that is particularly suited to a channel in which the transmitted signal is corrupted mainly by additive white gaussian noise (AWGN). The Viterbi decoding is one of two types of decoding algorithms used with convolutional encoding-the other type is sequential decoding. Sequential decoding has the advantage ....etc

A Low-Complexity SISO Multiuser Detector for Iterative Decoding of Asynchronous CDMA Systems With Convolutional Codes
Abstract”
The optimal decoding scheme for asynchronous codedivision multiple-access (CDMA) systems that employ convolutional codes results in a prohibitive computational complexity. To reduce the computational complexity, an iterative receiver structure was proposed for decoding multiuser data in a convolutional coded CDMA system. At each iteration, extrinsic information is exchanged between a soft-input soft-output (S ....etc

Base64 uses a 65 character subset of US-ASCII, allowing 6 bits for each character so the character m with a Base64 value of 38, when represented in binary form, is 100110. When a text string, let's say mne is encoded this is what happens : The text string is converted into its US-ASCII value. (In US-ASCII each character is assigned a value)

Error correction software for Bose-Chaudhuri-Hochquenghem (BCH) codes is optimized for general purpose processors that do not equip hardware for Galois field arithmetic. The developed software applies parallelization with a table lookup method to reduce the number of iterations, and maximum parallelization under a cache size limitation is sought for a high throughput implementation. Since this method minimizes the number of lookup tables for encoding and decoding processes, a large parallel factor can be chosen for a given cache size.The naive ....etc

ABSTRACT
Lightweight structure is a new trend in machine tool design to ensure higher speed and higher acceleration of elements. The drive and control systems in mechanical engineering requires lightweight design provided by the recently developed light materials thus resulting in economical advantages. The hollow-sphere-composites (HSCs) consist of hollow spheres up to 80 of the volume and a reactive resin system as binder. The recently developed HSC materials, the hollow sphere bodies, are made from ceramics, silic ....etc

Abstract
As the microprocessor speed increases from 500MHz to 1GHz and beyond, the designers must find new ways to make the cache memory for high speed access. Here, the clock to wordline path delay is optimized using a novel circuit
design technique. The delay is optimized by about 2.5 times at worst
case corner. Considering a memory element whose access time is 800ps and read and write operation occurs simultaneously in the same clock cycle, 18% improvement of the overall access time is observed. There is also a pre-decoding and p ....etc
