摘要：
Using of quantized channel state information on transmitter (CSIT) side for adaptive signal processing on base station (BS) side also called as precoding provides to reduce feedback channel bandwidth in comparison with full CSIT. There are many solutions for feedback channel quantization. The aim of this paper is to compare efficiency of known grassmannian manifold for codebook design and random vector quantization based codebooks using to transmit CSI from users to base station side.
