SUMMARY In-building power lines have often been considered as attractive media for high-speed data transmission, particularly for applications like home networking. In this paper, we develop models for power line channels based both on theoretical considerations and practical measurements. We consider power line channel frequency response and noise models… (More)
Recently in-building power lines have been considered as a medium for high speed data transmission for applications like home networking and internet access. Frequency selec-tivity and time variation of this medium in addition to the high level of narrow-band and impulsive interference makes multi-carrier modulation, and especially its popular variant… (More)
Efficient soft-decision decoding of Reed-Solomon codes is made possible by the Koetter-Vardy (KV) algorithm which consists of a front-end to the interpolation-based Guruswami-Sudan list decoding algorithm. This paper approaches the soft-decision Koetter-Vardy algorithm from the point of view of a communications systems designer who wants to know what… (More)
Two new algorithms for performing arithmetic coding without employing multiplication are presented. The first algorithm, suitable for an alphabet of arbitrary size, reduces the worst case normalized excess length to under 0.8% versus 1.911% for the previously known best method of Chevion et al. The second algorithm, suitable only for alphabets of less than… (More)
Delivering milliwatts of wireless power at centimeter distances is advantageous to many existing and emerging biomedical applications. It is highly desirable to fully integrate the receiver on a single chip in standard CMOS with no additional post-processing steps or external components. This paper presents a 2 × 2.18 mm(2) on-chip wireless power transfer… (More)
This paper provides a brief overview of semiconductor memory design from the perspective of the impact multiple-valued circuit techniques are making on modern day implementations. The focus is primarily on CMOS-related technologies.
In a Viterbi decoder, there are two known memory organization techniques for the storage of survivor sequences from which the decoded information sequence is retrieved, namely register exchange method and traceback method. This paper extends previously known traceback approaches describes two new traceback algorithms, and compares various traceback methods… (More)
The main problem with the hardware implementation of turbo codes is the lack of paral-lelism in the MAP-based decoding algorithm. This paper proposes to overcome this problem by using a new family of turbo codes called Multiple Slice Turbo Codes. This family is based on two ideas: the encoding of each dimension with P independent tail-biting codes and a… (More)
