Introduction

Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation system. The transmission channel is divided into a number of subchannel in which each subchannel is assigned a subcarrier. Conventional OFDM systems use IFFT and FFT algorithms at the transmitter and receiver respectively to multiplex the signals and transmit them simultaneously over a number of subcarriers. The system employs guard intervals or cyclic prefixes (CP) so that the delay spread of the channel becomes longer than the channel impulse response ....etc

Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional F ....etc

Accounting operates within a broad socio-economic environment, and so, the knowledge required of the accountant cannot be sharply compartmentalized.It is therefore, difficult to discuss one area without relating to other areas of knowledge. We place a great emphasis on the conceptual knowledge. The accountant should not only know but he should understand.
From the above it is clear that to define accounting as such, is rather difficult. Many accountants have defined Accounting in very many languages. However, we can consider the following defi ....etc

Abstract

The demand for high-speed mobile wireless communications is rapidly growing.
OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. This work presents an investigation into methods for maximizing the spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. The current standards such as IEE 802.11a in USA and H ....etc

comparative study of conventional and modern system of accounting ppt

application, rulings and methods have constantly evolved with the change of times, the principles of traditional marketing of Accounting services have remained the same for decades.

New applications of the traditional marketing principle are constantly being evolved. Many of these are very innovative indeed.

But it is the BASIC PRINCIPLE of traditional marketing that the change of times has rendered inefficient and nonfunctional.

That basic principle of traditional market ....etc

needs and importance of a comparative study of conventional and modern system of accounting

ACCOUNTING INFORMATION SYSTEMS

An accounting information system (AIS) combines the study and practice of accounting with the design, implementation, and monitoring of an information system. Such a system involves applying modern information technology resources to traditional accounting controls and methods to provide users the financial information necessary to manage their organizations. This system is often a component of an entity's management info ....etc
