Simulation results show that compared with fixed training interval schemes, the improved algorithm can achieve better BER (Bit Error Rate) performance while keeping lower system overhead.

与采用固定训练周期相比，该方法可以在保证比较低的导频开销的同时，使系统获得更好的误比特性能。

In addition, the spacing between the pulses in the start bit allows the receiver to measure the transmission rate; the rate does not need to be fixed in advance.

除此之外，也不必事先固定传输速率，因为接收器可透过起始位元内两脉冲之间的距离，测量出传输速率。

Most visual communication applications use a fixed rate transmission channel, which means the encoder's output bit rate must be regulated to meet the transmission bandwidth.

大多数视频通信应用都使用固定的传输带宽，这意味着编码器的输出码流受到传输带宽的限制。

Then there is life insurance, which at least seems to offer a guaranteed fixed rate of interest, plus a bit more in good years.

ECONOMIST: Not all it should be

Earlier this week, the Council of Mortgage Lenders said the main effect of FLS so far was to make fixed-rate mortgage deals, which account for about two-thirds of all new mortgage borrowing, a bit cheaper than before.
