Abstract
With the rapid advancement of wireless personal communication services, a new challenge to this industry is the integration of multiple systems and applications on a single device. Although a fourthgeneration wireless communication standard will address the goal of a global standardization once again, it is more realistic to anticipate a core standard plus several extensions, which might cover the integration of already deployed systems like GSM, the IMT-2000 standards, Hyper LAN, Blue Tooth, WLAN and the like. These systems differ in many respects. To begin with, they normally have incompatible air interface access techniques (TDD, CDMA, FDMA, TDD/CDMA, TDD/FDMA, OFDM), use different frequency bands and channel bandwidths, vary in their baseband receiver implementations (e.g. RAKE receiver for CDMA technology) and coding schemes. A transceiver, which can be totally redefined in software, is commonly known as software defined radio (SDR) [1]. However, an SDR approach which is based only on software reconfiguration seems too extreme to the author taking into consideration the estimated power consumption, which is still an essential problem in mobile transceiver design, of such an SDR based transceiver. Instead, we propose an approach which is based on reconfigurable hardware in the RF and in the baseband section combined with the exploitation of already possible readjustments of the transceiver software part. This approach is known as “flexible radio architecture” (FAR).
