CSE 561 Stage 1 Writeup

To facilitate efficient two-way communication, we implemented the sliding window algorithm with configurable send and receive window sizes. To ensure reliability of our transmissions, we detected corrupted packets using either a checksum or a CRC (cyclic redundancy check), as well using LDPC (low density parity check) to do error correction. And in addition to DBPSK (differential binary phase shift keying), we’ve also included two more bit-encoding techniques: DQPSK (differential quaternary phase shift keying) and GMSK (Gaussian minimum shift keying). Options for error detection and modulation type are determined at the command line.
