standard for broadband wireless access, known as Worldwide Interoperability for Microwave Access (WiMAX), provides high throughput over long-range transmission. The key developments in the physical (PHY) layer include Orthogonal Frequency-Division Multiple Access (OFDMA) and the Multiple-Input-Multiple-Output (MIMO) antenna technology, which enhance transmission quality and throughput. 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 (Fig. 7.6.7) that also includes an RF transceiver for MIMO WiMAX transmission. The baseband transmitter (Fig. 7.6.1) generates a WiMAX waveform according to the IEEE 802.16e Rev2 specification [1]. In this time-divisionduplex WiMAX system, the uplink subframe is composed of OFDM symbols of
