“…As a result, PAPR plays an important role in the design of wireless communication systems because power amplifiers are usually operated in the linear mode rather than the saturation mode. A bandlimited signal with high PAPR requires a large back-off to guarantee that the power amplifier operates inside its linear region in order not to distort the transmitted signals [7,38,39]. In addition, signals with high PAPR require higher dynamic ranges of digital-to-analog converters (DAC) at the power amplifier.…”

“…In the 3GPP LTE standard, the technologies being implemented consist of single carrier frequency division multiple access (SC-FDMA), as well as OFDMA. Both of these technologies are based on OFDM techniques; however, SC-FDMA is being recommended as the uplink access technology due to its lower PAPR [7,9,38,39]. To comply with the initial version of the IEEE 802. standard, which species the use of a single carrier system for frequency bands between 10 and 66 GHz, we propose the implementation of SC-FDMA as the transmission scheme to be implemented by the SNs for uplink and downlink.…”

“…At the input of the transmitter, a baseband modulator transforms the binary sequence to a multilevel In SC-FDMA, subcarrier mapping can be achieved using one of several existing methods. The most common methods are the localized and distributed subcarrier modes [7,9,38,39]. In the distributed subcarrier mode, the DFT outputs are spread over the entire bandwidth and zeros are introduced in the unused subcarriers.…”

“…For the different systems implemented, 10 5 uniform random symbol blocks were generated. Applying the criteria in [7,9], and [8], the PAPR of the the pulse shaping filter was measured and analyzed. After calculating the PAPR of each block, the Roll-off factor α = 0.22…”

Wireless technologies are an essential communication means that transform a branched localized fixed meshwork into a ubiquitous disconnected network. A clear trend shows that cells are becoming smaller, homogeneously distributed, operating at higher carrier frequencies, and more energy conscious. This points toward wireless picocell systems that implement millimeter-wave (mm-wave) modulation. In this work various techniques are proposed, which are oriented to specific traits of the 60-GHz mm-wave band. Two techniques oriented to solve physical and data-link layer issues are proposed. Single carrier frequency division multiple access (SC-FDMA) is proposed as the technology to be implemented at the physical layer, and a variable slot time multiplexing access technique, called variable slot time-time division multiple access (VST-TDMA), with a conscious energy-conservation protocol, is proposed for the data-link (MAC) layer. SC-FDMA with pulse shaping is implemented to minimize the peak-to-average power ratio of the system, which reduces energy consumption. The multiplexing access technique takes advantage of the reduced cell size by multiplexing data in the time domain, this allows the reduced number of users to utilize the entire available bandwidth. Incorporated into the access protocol is the option of energy pacing or even self-sustainability if an energy harvesting device is present. Self-sustainability can be achieved at the cost off throughput, some techniques are discussed to relieve this trade-off condition. Also, a thorough discussion is included on battery energy depletion, even with an energy harvesting device present, to further increase the through- put performance. Since using SC-FDMA reduces the energy consumption, it enables VST-TDMA to operate at higher speeds under self-sustainability mode. Overall the proposed set of solutions showed independently significant improvements to the system. It is also discussed how these techniques coalesce conveniently by working in unison, improving the energy efficiency and throughput capabilities of 60-GHz systems.Keywords 60 GHz · Energy self-sustainability · Millimeter-wave · Peak-to-average power ratio (PAPR) · Single carrier frequency division multiple access (SC-FDMA) · Variable slot time-time division multiple access (VST-TDMA)

Artículo de publicación ISIDigital communication systems are characterized by having a filter at the transmitter and receiver sides to band limit the transmitted signals and diminish the effects to intersymbol interference (ISI). The optimum parametric linear combination pulse is evaluated at the transmitter and receiver sides by using different evaluation tools. The proposed pulse is evaluated in terms of the bit error rate in the presence of symbol-timing errors. Eye diagrams are presented to visually evaluate the susceptibility of the transmission system to ISI, and the maximum distortion is determined as a numerical measure of performance.Program U-INICIA VID, University of Chile UI-02/201
