2)Rate compalible convolutional codes.
-rate compatible punctured codes
-nested convolutional codes

Answer 2

Answer:

ARQ means Automatic Repeat Request, when there are communications done between a sender and receiver and the sender and receiver are unknown of the fact, that the data sent is received by the receiver or not. In such scenario, ARQ proves to be very beneficial, where it sends the same data again, until any acknowledgment is not received by the sender from receiver.

Explanation:

ARQ has several types of protocols of sending data, one of  them is stop and wait ARQ, here the sender waits for a certain time period for receiving acknowledgement, and if it doesn't gets then the same data is sent again.
