This paper proposes an integrated DVB-H receiver architecture. The main focus has been low power consumption, aiming at handheld battery operated devices. The total power consumption for the RF tuner is estimated to be less than 20 mW with a duty cycle of 10%. The receiver uses a low-IF architecture and cover the receive bands from 470 MHz to 702 MHz, with an IF of 4.57 MHz. The proposed receiver meets the DVB-H requirements. The sensitivity is -88 dBm, the noise figure 5.7 dB and the adjacent channel protection ratio (ACPR) is -51 dB.

    ABSTRACT: This paper presents design methods for delta-sigma (ΔΣ) analog to digital (A/D) converters having signal-transfer functions (STFs) with improved out-of-band signal attenuation. The trade-off between the improved attenuation of the STF and achieving a noise-transfer function (NTF) that optimizes the SNR of the A/D converter is made explicit.

    ABSTRACT: This paper introduces a novel seamless handoff approach for DVB-H networks aimed at reducing the user terminal power consumption and at making the handoff algorithm be driven by the quality of the user received signal. This implies the substitution of standard RSSI-based procedures with a method based on the Modulation Error Rate (MER) monitoring. The additional use of an underlying cellular network, for DVB-H related data delivering, allows to achieve additional advantages: a superior power saving and a faster handoff execution. Obtained results suggest that the DVB-H handoff protocol design is an issue, which definitely deserves further investigation in the view of making DVB-H an effective solution for delivering broadcast content to mobile users.

    ABSTRACT: The phenomenon degrading reception performance of DVB broadcasting signal is caused by collocation of plural communication modules in the GSM-900 cellular phone with a built-in DVB-H receiver. This paper offers how to improve performance of the DVB-H receiver by applying digital filter that is using DSP techniques to cancel GSM signal interfering to the DVB-H receiver which is collocated in a single user's GSM terminal. In the demodulation part of the DVB-H receiver, the DVB reception performance can be greatly improved by removing interference components of GSM signal, which is flowed with DVB signal, to the noise cancellation filtering algorithm using difference of characteristics between GSM modulated signal and OFDM signal.
