high speed underwater acoustic modems is shown in this paper. high speed digital communication and broadband underwater acoustics technologies have been combined to achieve this . increased data rate and decreased power consumption is achieved by Broadband Spread Spectrum Technology. The underwater communication has to deal with noises such as offshore drilling noise, ambient noise, ship noise etc. no communication errors has been seen to appear with these noises.
Broadband Spread Spectrum Technology us implemented..............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 IEEE 802.11a in USA and ..............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 ..............etc

High Speed OFDM Packet Access

High Speed OFDM Packet Access (HSOPA) also called as super 3G can be said as the successor of HSDPA and HSUPA technologies specified in 3GPP releases 5 and 6. This expected fraction of 3GPP s Long Term Evolution (LTE) upgrade path for UMTS systems has given a totally different air interface system with that of the W-CDMA.

The characteristics of HSOPA includes -:

· Utilizes 1.25 MHz to 20 MHz bandwidth compared with the 5MHz usage of W-CDMA.

· T..............etc
