In the wireless broadband network, most traffic are generated from indoor, and the indoor coverage is identified as the major bottleneck especially in dense urban environment with high-rising buildings. In this paper, the TD-LTE network downlink performance of indoor is studied with various deployment options, including outdoor Macro and Micro cell, indoor(More)

AMC (Adaptive Modulation and Coding) is an important technology adopted by IEEE 802.16. Based on AMC, we introduce a frequency domain scheduling and subchannel resource allocation algorithm (FDSA) in this paper for IEEE 802.16 OFDMA systems. According to this algorithm which is applied in physical layer, the paper also proposes a simple AMC link adaptive(More)
Codebook design has been investigated extensively over the past few years for quantized precoding in MultipleInput Multiple-Output (MIMO) communication system. Grassmannian line packing (GLP) codebook is widely used in industry and literature. Traditional GLP codebook can only show good performance in spatial uncorrelated channel. But the practical channel(More)
