This work proposed a highly compact multi-bands antenna design based on the coupled meander-line folded monopole for M2M applications. This novel antenna is design to cover GSM / DCS / PCS / PHS (900 / 1800 / 1900 MHz), WCDMA / IMT-2000 (1920-2170 MHz), and Zigbee / Blutooth / WLAN (2450 MHz), and WiMAX / WLAN (5150-5350 MHz) with the physical size of 70 mm × 11.4 mm × 0.8 mm. Good agreement between...

There are a few representative wireless network access technologies used widely. WCDMA is third generation technology of mobile communication technology supporting high mobility and broad service area. WLAN supports high data rate similar to wired network, and DVB-H supports both data and broadcasting services correspondingly. However, these technologies include some limitations especially on the...

In this paper, we propose a cross-layer optimization approach that exploits retransmission diversity in wireless CDMA communications. Conventionally, data packets that are not correctly detected are usually dropped. These dropped packets can be used to help data packet detection. By exploiting all the retransmitted packets, data packets can be correctly detected with higher probability. The proposed...
