Frequency Diverse Array OFDM Transmitter for Secure Wireless Communication

A generic transmitter for wireless OFDM systems

To fully utilize the available spectrum for a wireless communication system it is feasible to adapt to different situations on the channel as well as different systems with various quality of service. In this paper a generic OFDM transmitter is presented and it is shown that high flexibility can be obtained with a reasonable amount of additional hardware. Part of the design, the FFT-processor, ...

Frequency Scaled Time Domain Equalization for OFDM in Wireless Communication

In this paper, the use of Orthogonal Frequency Division Multiplexing (OFDM), combined with a Time Domain Equalizer (TEQ), is investigated for broadband fixed wireless access systems. OFDM systems use a Cyclic Prefix (CP) that is inserted at the beginning of each symbol to convert the linear convolution of data and channel into a circular one. If the CP is longer than the channel length, Inter S...

OFDM ( A ) for wireless communication

This report is a tutorial on Orthogonal Frequency Division Multiplex (OFDM) and Orthogonal Frequency Division Multiple Access (OFDMA). OFDMA is the major transmission and access technology for future mobile broadband systems like Mobile WiMAX and 3GPP Long Term Evolution (LTE). One of the key features of OFDM and OFDMA is the ability to handle multipath propagation without complex receivers. Th...
