Remote controls come in many different sizes, shapes and wireless technologies and are widely used in the consumer market as accessories for a wide range of products, such as televisions, video games, stereo systems, lighting controls and home automation including garage door/gate openers, air conditioning units, fans and automobiles with remote keyless entry (RKE) key fobs. The most common rem...

This paper presents propagation measurements results using Integrated Services Digital Broadcast-Terrestrial (ISDB-T) to investigate the characteristics of 6MHz wideband Digital Terrestrial Television channel at 677 MHz for fixed and portable reception. Empirical measurements were done at predetermined measurement points consisting of 21 radials for a total of 92 locations extending to 20 kilom...

of the United States: 2006, section 8, page 273, Table 417.

In this paper, we present a prototype transmitter and receiver with set partitioning (SP)-64 amplitude phase shift keying (APSK) coded modulation developed for expanding satellite transmission capacity. SP-multi-level is scheme that can improve noise immunity by properly combining scheme, bit allocation, error-correction codes. We designed SP-64APSK on the basis of channel capacity confirmed it...

Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems)  are possible alternatives to provide security for such applications. In this paper, we consid...

This paper uses data from the FCC and the 2000 USA Census to estimate the actual white space (in terms of area/population recovered) available for cognitive radios in TV bands in the continental USA. The available white space is the intersection of white spaces resulting from two different viewpoints. The “pollution” viewpoint reflects the cognitive radios’ perspective: where is interference fr...
