BF_QPSK.rar - Codebook is a known matrix, had been create and setup when initial design a system. Each column in codebook specifies a beamforming weight vector, or in other words, specifies a combination for the phase shifters and amplitude controllers to create a respect radiation pattern. All columns should span the entire space around the beamformer (the device that steers the beam), 360 degree with 1-D array antenna and sphere space with 2-D array. This requirement ensures wherever the beamformee (the target device of the steered beam) locates, there is a weight vector steers the beam to it and keep the channel in good condition. To reduce the complexity and electrical elements, in this paper we consider only the phase in 1-D array antenna by controlling the phase shifters, without examining the amplitude of the signal.,2015-08-26 11:37:23,下载6次

BF_M_QAM.rar - Introduction
This section builds an example step-by-step to give you a first look at the Communications System Toolbox™ software. This section also shows how Communications System Toolbox functionalities build upon the computational and visualization tools in the underlying MATLAB® environment.
Modulate a Random Signal
This example shows how to process a binary data stream using a communication system that consists of a baseband modulator, channel, and demodulator. The system s bit error rate (BER) is computed and the transmitted and received signals are displayed in a constellation diagram.
The following table summarizes the basic operations used, along with relevant Communications System Toolbox and MATLAB functions. The example uses baseband 16-QAM (quadrature amplitude modulation) as the modulation scheme and AWGN (additive white Gaussian noise) as the channel model.,2015-08-26 11:32:48,下载2次
