bit error rates
The throughput of LANs with the DCF mechanism under high load and in noise is evaluated by an analytical method, which ensures high estimation accuracy for any values of protocol parameters and bit error rates.
      
TCP performs poorly in wireless mobile networks due to large bit error rates.
      
An open eye 20?Gb/s operation with bit error rates better than 10-12 has been achieved in a temperature range 25-85?°C without current adjustment.
      
Comparison of bit error rates between the modified SSW algorithm and conventional bit detection shows that the modified algorithm is much more robust against the host interference.
      
The bit error rates (BER) of different dispersion managed systems, which induced by the timing jitter are given and compared.
      
A common problem of all wireless digital datatransmission systems is the bit error rates of the radiosubsystem, which can be several orders of magnitudehigher than for a wire- or fiber-based technology.
      
TULIP is exceptionally robust when bit error rates are high; it maintains high goodput, i.e., only those packets which are in fact dropped on the wireless link are retransmitted and then only when necessary.
      
Bit error rates with respect to different ON-OFF ratios and extinction ratios are also evaluated.
      
Wireless transmission imposes constraints not found in typical wired systems such as low power consumption, tolerance to high bit error rates, and scalability.
      
However, for wireless, higher bit error rates are quite common due to shadowing and other fading effects.
      
To devise this scheduling method, we formulate a globally optimizing integer program that maximizes the total weighted sum of all best-effort transmissions in the entire system, keeping in view the diverse target Bit Error Rates for each one.
      
The obtained numerical results of investigating 802.11 LANs by the developed method are validated by simulation and show high estimation accuracy for any values of protocol parameters and bit error rates.
      
This intuition is confirmed by employing a variable-rate adaptive modulation scheme for the eigen-transmission and comparing its spectral efficiency with that of orthogonal space time block codes (OSTBCs) at specific target bit error rates.
      
The results presented are received bit error rates from Monte Carlo simulations.
      
Bit error rates (BER) for rake receiver with equal gain combining and postdetection integrator are presented.
      
The performance evaluation is based on Monte Carlo simulations of data transmission and average bit error rates versus the average signal to noise ratio per net information bit are presented for different array configurations.
      
The bit error rates (BER) of the decorrelating, parallel interference canceler (PIC) and groupwise serial interference canceler (GSIC) with either PIC or decorrelator within the group are compared.
      
The performance of BPSK, QPSK, and 16QAM modulation formats are compared and analytical and simulation results are presented in terms of the bit error rates (BER) for these different modulation formats.
      
We again find that the framed referential coding scheme exhibits good performance that can lead to significant header compression and packet drop savings for reasonable bit error rates.
      
However, propagation impairments can cause severe degradation in bit error rates (BER) for coherent detection.
