The present invention relates to a method for transmitting, by a base station, a downlink signal using a plurality of transmission antennas comprises the steps of: applying a precoding matrix indicated by the PMI, received from a terminal, in a codebook to a plurality of layers, and transmitting the precoded signal to the terminal through a plurality of transmission antennas. Among precoding matrices included in the codebook, a precoding matrix for even number transmission layers can be a 2×2 matrix containing four matrices (W1s), the matrix (W1) having rows of a number of transmission antennas and columns of half the number of transmission layers, the first and second columns of the first row in the 2×2 matrix being multiplied by 1, the first column of the second row being multiplied by coefficient “a” of a phase, and the first column of the second row being multiplied by “−a”.

A method and apparatus detects and estimates geo-observables of navigation signals employing civil formats with repeating baseband signal components, i.e., “pilot signals,” including true GNSS signals generated by satellite vehicles (SV's) or ground beacons (pseudolites), and malicious GNSS signals, e.g., spoofers and repeaters. Multi-subband symbol-rate synchronous channelization can exploit the full substantive bandwidth of the GNSS signals with managed complexity in each subband. Spatial/polarization receivers can be provided to remove interference and geolocate non-GNSS jamming sources, as well as targeted GNSS spoofers that emulate GNSS signals. This can provide time-to-first-fix (TTFF) over much smaller time intervals than existing GNSS methods; can operate in the presence of signals with much wider disparity in received power than existing techniques; and can operate in the presence of arbitrary multipath.

A network equipment test device includes per-UE uplink signal generation processing chains for generating per-UE time domain uplink signals. Per-UE signal faders simulate per-UE signal fading for the per-UE time domain uplink signals. Different phases and amplitudes are used over time to simulate different signal fading. Fourier transformation units perform Fourier transformation of each of the time domain uplink signals to produce per-UE frequency domain uplink signals with simulated per-UE signal fading. A subcarrier mapping unit performs subcarrier mapping of the per-UE frequency domain uplink signals to produce a frequency domain multi-UE uplink signal with simulated per-UE signal fading. An inverse Fourier transformation unit performs inverse Fourier transformation of the frequency domain multi-UE uplink signal to produce a multi-UE time domain uplink signal with simulated per-UE signal fading. A network interface transmits the time domain multi-UE uplink signal with simulated per-UE signal fading to the DUT.
