Adaptive Channel Equalization for Wireless Personal Communications
In this paper, a new adaptive H1 filtering algorithm is developed to recursively update the tap-coefficient vector of a decision feedback equalizer (DFE) in order to adaptively equalize the time-variant dispersive fading channel of a high-rate indoor wireless personal communication system. Different from conventional L2 [such as the recursive least squares (RLS)] filtering algorithms which mini...
متن کاملEqualization Techniques for Broadband Wireless Networks
Wireless sensor networks (WSNs) are characterized by low-power devices equipped with communication capabilities. Due to the lack of a set infrastructure, WSNs exhibit characteristics fundamentally different from traditional networks. The existing literature in conventional wireless networks, therefore, cannot be applied to WSN design. The recently introduced Cooperative diversity techniques exp...
متن کاملNovel Techniques of Single-Carrier Frequency-Domain Equalization for Optical Wireless Communications
We investigate the use of single carrier frequency domain equalization (SCFDE) over a diffuse optical wireless (DOW) communications. Recently orthogonal frequency division multiplexing (OFDM) has been applied to DOW communications. However, due to high peak-to-average power ratio (PAPR), the performance of OFDM can severely be affected by the nonlinear characteristics of light emitting diodes (...
متن کاملFrequency-Domain Equalization and Channel Estimation for Broadband Wireless Communications
New services such as high-speed data transmission and multimedia applications have tremendously increased the bandwidth requirements for communications in the last two decades. On the other hand, the emerging need for access to information everywhere at every time (ubiquity) has focused attention over wireless communications. At the physical layer, wireless broadband transmission is characteriz...
متن کاملLow Complexity Turbo Equalization for High Data Rate Wireless Communications
Soft interference cancellers (SICs) have been proposed in the literature as a means for reducing the computational complexity of the so-called turbo equalization receiver architecture. Soft-input-soft output (SISO) equalization algorithms based on linear filters have a tremendous complexity advantage over trellis-diagram-based SISO equalizers, especially for high-order modulations and long-dela...
