ECE 6607 Homework #1 Due on September 7
Consider a tandem network with L links. All the links have the same rate C bps and the same propagation time p . The source has M bits to transport to the destination, and it divides them into equal-size packets. Ea
ECE 6607 Homework #2 Due on September 16 1. Consider the two-dimensional bit-check error-detection scheme. Would it be possible to correct every error in two bits? 2. Consider the general linear code for forward error correction. Derive the tightest-possi
ECE 6607 Homework #3 Due on September 30 1. Consider a 128K bits-per-second link carrying 1,500-byte packets over a satellite link. Compute the eciency of the go-back N protocol for the following values of Ws : (i) Ws = 1 (the stop-and-wait protocol); Ws
