CC1310: How is the BER calculated in the SmartRF studio application and what is the length of CRC?

Part Number: CC1310

Hello,

Can you tell me how is the BER calculated in the SmartRF studio application and what is the length of CRC?

Thank you

  • Hello,

    from source: www.ti.com/.../swru194b.pdf

    When the other device has started sending packets (see next slide), observe the
    number of packets received OK and not OK at the right bottom of the Packet RX
    panel. The NOK counter will be incremented if the receiver detects that packets
    are lost (requires that the transmitter includes a sequence number in the payload)
    or if a received packet has a CRC error. The PER value is calculated using the
    formula:
    PER = # packets NOK / (# packets OK + # packets NOK)

    CRC is one bit

    The most significant bit of the second byte is the CRC valid bit. If the bit is 1, CRC is OK. If it is 0, there is a CRC
    error in the received packet (i.e. one or more bit errors).

  • Hello AB,

    Thank you! so it is a 16 bits CRC? I was actually asking for the BER. How is it calculated? 

    Thanks again,

  • Hello,

    The CRC is 16bit.

    The relationship between PER, BER, and bits is as follows:

    PER = 1-((1-BER)^(#bits))
