Sentence examples for tap channel from inspiring English sources

Indeed, since each tag transmits in a narrow band channel (640 kHz), its channel can be modeled as a single tap channel [25].

Specifically, we model the UHF channel as a single tap channel [25], since each tag transmits in a narrow band channel (640 kHz).

The BPSK modulated data is applied at the input of the single tap channel and the output and Channel coefficients (400k samples) are stored in the SDRAM of TMS320C6416 DSP Board in real time.

Although this condition is met for any in a single tap channel, in a frequency selective channel, is typically taken as a small number (e.g., in the WiMAX UL-PUSC system is defined as 3).

The simulation parameters for the MIMO-OFDM system with two transmit antennas and two receive antennas are given in Tables 1 and 2. L = 8 tap channel whose taps are independent, identically distributed and correlated in time with a correlation function according to Jakes model [21, 22] is chosen by assuming there are fd = 5 and fd = 10 Hz.

where ∈ is the carrier frequency offset (CFO) normalized to the OFDM subcarrier spacing, τ is the timing offset, h(k) represents the k th tap channel impulse response, K is the number of taps in the channel, and w(n) is a complex AWGN sample.

Fig. 2 Wire-tap channel model.

When zmult is used, it is computed based on the 17-tap channel model detailed above.

Figure 5 Scenario 3's secrecy rate of the MIMO relay wire-tap channel and MIMO wire-tap channel, versus SNR: different antennas configurations ( N s, N r, N d, N e ) and ( N s, N d, N e ).

That is because the noisier the eavesdropper's channel, the better secrecy results are. Figure 6 Scenario 3's secrecy rate of the MIMO relay wire-tap channel and MIMO wire-tap channel, versus SNR: different noise values.

Furthermore, the secrecy capacity for different kinds of channels, such as the Gaussian wire-tap channel and the multi-input multi-output (MIMO) wire-tap channel, have been studied in [5, 6].
