OFDM based Foreign Agent for Communication between Wired and WIMAX Network

Spectrum Regrowth for OFDM-based LTE and WIMAX Systems

Streaming agent for wired network/wireless link rate-mismatch environment

It has been shown that an agent located at the junction of wired and wireless links can help streaming media systems identify where packet losses occur and therefore maintain proper endto-end congestion control. In this paper, we further expand the functionality of such agents in two ways. First, they allow streaming servers to identify the allowed transmission rate in both the wired and wirele...

MIMO-OFDM for LTE, WIFI and WIMAX

We dedicate this monograph to the numerous contributors of this field, many of whom are listed in the Author Index The MIMO capacity theoretically increases linearly with the number of transmit antennas, provided that the number of receive antennas is equal to the number of transmit antennas. With the further proviso that the total transmit power is increased proportionately to the number of tr...

Sdr Based Mimo-ofdm System for Future Wimax

MIMO technologies with OFDM air interface lead to a very compelling high-speed data transmission for future wireless systems. Since performance verification of MIMO system is important, Software Based Radio(SDR) -based MIMO testbed becomes essential to validate the theoretical performance gain. In this paper, we present SDR-based MIMO testbed system developed in the framework of SK Telecom. The...

BER analysis of OFDM based WIMAX using Punctured Convolutional codes

In this paper, simulation model of OFDM based WIMAX system has been developed using punctured convolutional codes. The bit error rate performance of fixedWIMAX has been carried out for different modulation techniques like BPSK, QPSK, and QAM16 with different code rates 1/2, 2/3, 3/4 in each case of modulation technique. Puncturing is the process of deleting some parity bits from the code-word a...
