Channel Adaptive Ofdm Systems with Packet Error Ratio Adaptation
نویسندگان
چکیده
MIMO-OFDM systems with pre-filtering as well as bit and power loading have gained a lot of interest recently. These systems are based on theoretically optimal solutions maximizing the uncoded throughput and constraining the maximum uncoded BER. In this paper, we extend the existing frameworks to coded systems with bit and packet error ratio adaptation. We evaluate the performance of this approach in a standard compliant WiMAX link level simulator.

This paper presents an empirical mode decomposition (EMD) based adaptive filter (AF) for channel estimation in OFDM system. In this method, length of channel impulse response (CIR) is first approximated using Akaike information criterion (AIC). Then, CIR is estimated using adaptive filter with EMD decomposed IMF of the received OFDM symbol. The correlation and kurtosis measures are used to sel...

In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce the PAPR.The coded bits at the input of OFDM modulator are separated into two groups of the Most Significant Bits (MSB) and the LeastSignificant Bits (LSB). The bits are mappe...
