精选示例
LTE Transmitter Using Software Defined Radio
Generate a reference measurement channel (RMC) downlink (DL) LTE waveform suitable for over-the-air transmission. This example also shows how to use a software-defined radio (SDR) to transmit the generated waveform using single or multiple antennas.
LTE Receiver Using Software-Defined Radio
Recover the master information block (MIB) and basic system information from an over-the-air LTE downlink (DL) waveform. This example also shows how to receive an LTE waveform using a software-defined radio (SDR) with single or multiple antennas.
Estimate Direction of Arrival Using MUSIC Algorithm and TwinRX Daughterboard
Estimate the direction of arrival of a signal with MUSIC algorithm using X300/X310 USRP™ radio with TwinRX daughterboard.
Alamouti Coding Based MIMO Transmitter using USRP Radio
Demonstrates the implementation of a 2x2 Multiple Input Multiple Output (MIMO) transmitter based on Alamouti based Space-Time Block Coding (STBC) using a USRP™ radio. The MIMO transmitter combines a training signal with a QPSK-modulated payload and then transmits over the air. The Alamouti Coding Based MIMO Receiver Using USRP Radio example receives and demodulates the signal transmitted by this example.
Alamouti Coding Based MIMO Receiver Using USRP Radio
Demonstrates the implementation of a 2x2 multiple input multiple output (MIMO) receiver based on Alamouti space-time Block Coding (STBC) using a USRP™ radio. The MIMO receiver processes the received signal and decodes the QPSK-modulated payload that the Alamouti Coding Based MIMO Transmitter using USRP Radio example sends using Alamouti STBC. You can also validate the performance of the 2x2 MIMO receiver in terms of bit error rate (BER).
