Fiber laser technology has been demonstrated as a versatile and reliable approach to source manufacturing with wide range of applicability in various fields ranging from science industry. The power/energy scaling single-fiber systems faced several fundamental limitations. To overcome them boost the level even further, combining output powers multiple lasers become primary approach. Among techni...

In this paper, we investigate a new generalized selection combining (GSC) technique and an adaptive rake combining scheme to save the power consumption of mobile rake receivers for wideband CDMA systems. The new GSC technique called minimum selection GSC (MS-GSC) selects a minimum number of rake fingers, while maintaining the combined SNR larger than a given threshold. The proposed adaptive rak...

Adaptive modulation and diversity combining represents the enabling techniques for the future generation of wireless communication. Adaptive modulation is a transmission scheme in digital communications where the transmitter adapts its transmission mode in accordance with the channel. In TDD systems the channel state is known in the transmitter side because of channel reciprocity, hence the ada...
