This study presents a limited feedback codebook design for a multiple-input single-output (MISO) beamforming system in a Rician fading channel. To support the Rician fading channel, the physical characteristics of the channel are exploited in designing the codebook by Grassmannian line packing (GLP). To this end, a portion of the total codewords is allocated for supporting the line-of-sight (LOS)...
Erasure selection for errors-and-erasures decoding algorithms is investigated and analyzed, where declaring erasures provides additional gain for hard decision decoding. To derive an analytical criterion for optimal erasure selection, we first investigate erasure effects on decoding performance, by which a metric function for erasure selection is derived. From the derived metric, a suboptimal threshold...
