Read the following work proposal from Writing Effective Work Proposals by Ted Knoy for an electrical engineering-related (電子相關分類) project:

 

Despite a large frequency offset, wide range locking with fast

[                    ( xiv )

acquisition circuit-designed carrier recovery helps a digital

 

receiver to lock the carrier frequency in a short time with a

 

tolerable error rate. However, conventional methods cannot do

                     ] [                 ( xii )

so just by utilizing a digital phase-locked loop (PLL) circuit 

 

since the loop filter is a one-order low-pass filter. While a loop

                                                     ] [

filter with a wide bandwidth causes large vibration and

                         (  xvi  )

ultimately a high error rate, a loop filter with a narrow

 

bandwidth leads to slow convergence that takes over ten times

 

longer than the estimated acquisition time. Furthermore, a loop

                                             ] [

filter with a narrow bandwidth may not recover the carrier

                   ( x )

while the receiver suffers from a large frequency or phase

 

offset, leading to failure in the digital receiver.

                                                  ]

Based on the above, we should develop a numerical method to

[                             ( xviii )

choose efficiently the bandwidth of the loop filter in the PLL

 

circuit. An additional apparatus can also be developed in the

carrier recovery circuit to estimate offsets precisely. To do so,

                                                          ] [

a frequency detection apparatus can be used in the carrier

                          (  viii  )

recovery circuit to lock the large frequency offset. The PLL

 

circuit can then automatically switch the coefficients of the

 

loop filter into distinct bandwidths to reduce vibration and to

 

converge faster than conventional circuits. As anticipated, the

                                             ]  [

novel design can lock a wide range of offsets of more than 100

                    ( ii )

KHz in a short acquisition time with a symbol error rate of less

 

than 0.01. The improved carrier recovery on a digital receiver

         ]  [               (  iv  )

can track better than conventional models, making

 

telecommunication products more competitive.
