    Digital TV broadcasting from the stratosphere was tested using an unmanned aerial vehicle, a Pathfinder Plus. A television transmitter installed under the wing transmitted a UHF band signal as the vehicle flew at an altitude of 20 km. The Japanese digital terrestrial broadcasting standard (ISDB-T) was used for transmission. The 13.5-hour flight time included 3 hours of transmission testing. The tr... View full abstract»

    Estimation and tracking of the frequency-selective time-varying channel response is a challenging task for wireless communication systems incorporating coherent OFDM. In pilot-symbol-assisted (PSA) OFDM systems, the minimum mean-square-error (MMSE) estimator provides the optimum performance based on the channel statistics (channel correlation function and SNR). In OFDM systems, FFT-block timing er... View full abstract»

    We proposed and demonstrated a four-wavelength bi-directional dense-wavelength-division-multiplexing (DWDM) CATV system that uses chirped fiber gratings (CFGs) as the dispersion compensation devices to reduce the fiber dispersion and cross-phase modulation (XPM)-induced crosstalk simultaneously. Our proposed system not only reduces the required number of fibers, but also offers the advantages of c... View full abstract»

    Some performance results of the Cartesian feedback and feedforward linearization techniques applied to a class-A power amplifier operating at 28 GHz are presented. The performance of the combination of HMMC-5040 (driver) and HMMC-5033 (power amplifier) is used as benchmark for simulation analysis. This analysis is addressed to show the key aspects on spectral regrowth due to phase margin and loop ... View full abstract»

    Recent advances in technology have resulted in a significant growth in wireless communications, which have resulted in a strong demand for reliable transmission of video data. The challenge of robust video transmission is to protect the compressed data against hostile channel conditions while bringing little impact on bandwidth efficiency. Here, using macroblock (MB)-based segmentation results, we... View full abstract»

  • Height gain measurements for DTV reception in Singapore

    Publication Year: 2004, Page(s):396 - 398

    Very few height-gain measurements have been made especially in built-up areas. Measurements made in Singapore confirm that the height-gain is different in different locations and depends on the local clutter, ground reflection and the radiation pattern of the transmitting antenna. In high rise HDB (Housing Development Board) estates, height loss is observed instead of gain. View full abstract»

  • Compensation of phase noise in OFDM systems using an ICI reduction scheme

    In Orthogonal Frequency Division Multiplexing (OFDM) communication systems, the local oscillator phase noise introduces two effects: common phase error (CPE) and inter-carrier interference (ICI). The correction of CPE does not suffice always, especially when high data rates are required. Through the creation of a frequency-domain linearized parametric model for phase noise, we generate an ICI redu... View full abstract»

  • Performance investigation of STBC-OFDM with code-division multiplexing in time-varying channels

    Orthogonal frequency division multiplexing (OFDM) is sensitive to carrier frequency offset and channel estimation error, which destroy the subcarrier orthogonality and give rise to intercarrier interference (ICI). This paper addresses the performance degradation due to imperfect parameters in an orthogonal frequency and code division multiplexing (OFDM-CDM) system with multiple transmit antennas. ...

    A combining of MIMO signal processing with OFDM is regarded as a promising solution of enhancing the performance of next generation wireless system. Therefore, in this paper, an OFDM-based wireless system employing layered space-time architecture is considered for a high-rate transmission. With an emphasis on a preamble design for multi-channel separation, we address a channel estimation based on ... View full abstract»

    Orthogonal frequency division modulation (OFDM) system is very useful for the multi-path channel and highly bandwidth-efficient system. However, OFDM signal shows the high peak to average power ratio (PAPR) so that nonlinear distortion can happen in the high power amplifier (HPA). This paper studies BER performance variation according to input back off (IBO) values when the predistorter is used fo... View full abstract»
