Unformatted text preview: codewords. Then for those particular codewords, but not the others, a double bit error could be corrected. 8.6 An ( n , k ) block code encodes k data bits into n-bit codewords. 8.7 An ( n , k , K ) code processes input data k bits at a time and produces an output of n bits for each incoming k bits. The current output of n bits is a function of the last K × k input bits. 8.8 A trellis is a diagram that shows the state transitions over time in a convolutional code. 8.9 Detection of errors and retransmission of frames that are received in error. 8.10 Go-back-N ARQ is a form of error control in which a destination station sends a negative acknowledgment (NAK) when it receives an error. The source station receiving the NAK will retransmit the frame in error plus all succeeding frames transmitted in the interim....
