BER and BLER initial measurement

• VSG can generate arbitrary signal. It's not limited by mac format. VSG can allocate a pdu full of data. And we use a fixed pattern to fill the pdu.

• The maximum size of a pdu is 2K (11 bit). The whole downlink zone can be fully utilized.
• We require BER resolution to 10^(-9). It corresponds to 30 bits in denominator counter. If we assume BLER as the calculation unit, the BLER resolution has to be 24 bits.
• The input pattern can be fill 0 and 1.
  

php + mailenable

Some articles suggested to change smtp setting sections to enable mail() function. Here I use MailEnable to achieve a better solution if the smtp server takes authentication phrase.

We still keep smtp=localhost in php.ini. So mail() will send messages to localhost smtp server. We need a relay agent to relay the message to the external sendmail server. MailEnable is a freeware that can be configured to do this.

What I did is to set up smart host, which you can access by MailEnable admin tool-->MailEnable Management --> server-->smtp-->properties.
Click the tab smart host in the form. Give the right smtp server and port . Check 'remote server requires authentication'. Enter your key and pass. Check smart host takes priority. You are all set.

One feature in mailenable is that it can't take angle brakets <> as the from address. It will bracket its own.
