WiMAX Channel Estimation: Algorithms and Implementations
Source: Freescale Semiconductor
This paper presents proposed uplink channel estimation algorithms for worldwide interoperability for microwave access (WiMAX) systems (IEEE Std. 802.16). It also presents parallelized implementations in Baseband Signal Processor 1 (BSP1). Currently, the Orthogonal Frequency Division Multiplexing (OFDM) modulation technique is applied extensively to high-speed wireless communication systems because of its advantages in mitigating the severe effects of frequency-selective fading, its high rate transmission capability, and its high bandwidth efficiency.
