Diversity technique in wireless communication
WebJun 5, 2012 · This chapter focuses on common methods used at the transmitter and receiver to achieve diversity. Other diversity techniques that have potential benefits beyond these schemes in terms of performance or complexity are discussed in [1, Chap. 9.10]. Diversity techniques that mitigate the effect of multipath fading are called … WebThese techniques are often used in combination to achieve maximum throughput and scalability. Spatial Diversity. In spatial diversity, multiple antennas separated at the ends of a communication system (by at least 1/2 wavelength) can give the requisite diversity gain. Transmit diversity and receiver diversity are both categorized under the ...
