Method and apparatus for adjusting a symbol decision threshold at a receiver in a communication network

A method of adjusting a symbol decision threshold at a receiver in a communication network, the method comprising the steps of:

• receiving a signal by the receiver, the signal containing a data component and an error component;
• counting a number of ones or zeros of the error component to isolate the number of ones or zeros of the error component;
• and
• utilizing the counted number of ones or zeros of the error component to adjust a symbol decision threshold at the receiver;
• wherein the step of counting a number of ones or zeros of the error component comprises the steps of:
• counting a number of ones or zeros of the received signal;
• correcting the received signal to remove the error component from the signal to isolate the data component;
• counting a number of ones or zeros in the data component;
• and
• comparing the number of ones or zeros in the data component with the number of ones or zeros of the received signal to isolate the number of ones or zeros in the error component;
• wherein the received signal is scrambled;
• the method further comprising the step of unscrambling the signal before performing the step of correcting the received signal to remove the error component.
