In this paper, we present a WiMAX baseband SoC implemented in 90nm and capable of high-speed transmission at 300km/h. This SoC is integrated in a USB device that also includes an RF transceiver for MIMO WiMAX transmission. The baseband transmitter generates a WiMAX waveform according to the IEEE 802.16e Rev2 specification. In this time-division duplex WiMAX system, the uplink subframe is composed...
The advance of wireless communications brings in various schemes of wireless digital communication technology. In the field of digital radio broadcasting, several specifications have been proposed, such as Eureka-147 and DRM (Digital Radio Mondiale). These systems require new spectrum assignment, which is a huge cost due to depletion of the available spectrum. Therefore, the IBOC (In-Band On-Channel)...
