Multiuser Diversity Gain in Orthogonal Frequency Division Multiplexing under Limited Channel Information Feedback

Pp. 303-343 (41)

Seokhyun Yoon

Abstract

Dynamic resource allocation and throughput behaviour of multiuser OFDM will be considered with three limited CSI feedback schemes, namely sub-channelized OFDM, 1-bit/sub-carrier and selective feedback. It should be noted, however, that our aim is not to compare them in strict sense, i.e. comparison of throughput for a fixed amount of feedback. In fact, these limited feedback schemes are not technically conflicting, but can be used simultaneously for further reduction in feedback overhead, and our objective is to provide insight into the system behaviour under the limited feedback schemes by exploring the relationship between the throughput and the respective design parameters.
