(Application Specific Integrated Circuit) solutions have been widely used to implement communication systems

1.0 Overview Application using frequency analysis of discrete-time signals in digital signal processor is the most convenient method especially in general-purpose digital computer or specially designed digital hardware (Proakis and Manolakis,

2.4 Cyclic extension and guard interval insertion One way to prevent inter-symbol-interference in channel which caused by delay spread is to create an extended guard interval between each OFDM (Morrison et.al,

3.1 The Discrete Fourier Transform Due to the importance of Discrete Fourier Transform (DFT) in signal processing application, it is critical to have an efficient method to compute this algorithm (El-Khashab and Swartzlander,

3.2.1 Divide and Conquer Divide-and-Conquer approach is adopted in FFT algorithm to make the computation more efficient

Figure 1.1: Interpretation of the Fourier Transform (Brigham,

In recent development of communication system, OFDM is proposed as the primary modulation method

PALANIAPPAN Thesis submitted in fulfillment of the requirements for the degree of

The basic idea of OFDM is to divide the available spectrum into N orthogonal subchannels. The digital baseband blocks (Proakis

the way the Fourier integral is defined, not every function s(t) can be transformed to S(f) . Therefore, two sufficient conditions are considered for the existence of Fourier transforms
