1Equalization of Linearly Frequency-Selective Fading Channels
"... Abstract—A simple technique for removing intersymbol inter-ference (ISI) introduced by “linearly frequency-selective ” fading channels is presented. The technique involves the optimization of the overall impulse response of the transmit and receive filters and effectively reduces the channel to o ..."

Optimized Delay Diversity for Frequency-Selective Fading Channels
- IEEE TRANS. ON WIRELESS COMMUN
, 2005
"... This paper proposes an optimized delay diversity (ODD) scheme for frequency-selective fading channels. The novel scheme requires knowledge of the channel impulse response (CIR) autocorrelation matrix at the transmitter, but the CIRs themselves have to be available only at the receiver side. A cost f ..."

A Nonlinear and Frequency-selective Fading Channel
"... Abstract—Orthogonal frequency division multiplexing (OFDM) is adopted for several wireless network standards due to its high capacity and robustness against multipath fading. OFDM, however, has a problem with high peak-to-average power ratio (PAPR) that strictly limits its application. Recently, OFD ..."

and discuss the trade-off for OFDM/TDM using MMSE-FDE between the channel capacity and the PAPR in a nonlinear and frequency-selective fading channel. Our results show that OFDM/TDM using MMSE-FDE achieves a larger capacity with a lower PAPR in comparison with the conventional OFDM. It is also shown
Effective Capacity Channel Model for Frequency-selective Fading Channels
"... To efficiently support quality of service (QoS) in future wireless networks, it is important to model a wireless channel in terms of connection-level QoS metrics such as data rate, delay and delay-violation probability. To achieve this, in [7], we proposed and developed a link-layer channel model te ..."

termed effective capacity (EC) for flat fading channels. In this paper, we apply the effective capacity technique to modeling frequency selective fading channels. Specifically, we utilize the duality between the distribution of a queue with superposition of N i.i.d. sources, and the distribution of a
Optimal Training for MIMO Frequency-Selective Fading Channels
- IEEE Trans. Wireless Commun
, 2002
"... High data rates give rise to frequency-selective channel effects. Space-time multiplexing and/or coding offer attractive means of combating fading, and boosting capacity of multi-antenna communications. As the number of antennas increases, channel estimation becomes challenging because the number of ..."

1Minimum SER Block Precoding and Equalization for Frequency-Selective Fading Channels
, 2009
"... In this paper, we study the joint transmitter and receiver design problem over frequency-selective fading channels. Motivated by the conventional MMSE-DFE, we present a simple approximate ML decision feedback equalizer at the receiver. We then perform precoding in a downlink scenario at the transmit ..."

Optimal Training for Frequency-Selective Fading Channels
- in Proc. of Intl. Conf. on ASSP
, 2001
"... Many communications systems employ training, i.e., the transmission of known signals, so that the channel parameters may be learned at the receiver. This has a dual effect: too little training and the channel is improperly learned, too much training and there is no time left for data transmission be ..."

When the training and data powers are allowed to vary, we show that the optimal number of training symbols is equal
