Joint Source-Channel Coding for 6G Communications
文献摘要:
In order to provide ultra low-latency and high energy-efficient communication for intelligences,the sixth generation(6G)wireless communication net-works need to break out of the dilemma of the de-pleting gain of the separated optimization paradigm.In this context,this paper provides a comprehensive tutorial that overview how joint source-channel cod-ing(JSCC)can be employed for improving overall system performance.For the purpose,we first in-troduce the communication requirements and perfor-mance metrics for 6G.Then,we provide an overview of the source-channel separation theorem and why it may not hold in practical applications.In addition,we focus on two new JSCC schemes called the double low-density parity-check(LDPC)codes and the dou-ble polar codes,respectively,giving their detailed cod-ing and decoding processes and corresponding perfor-mance simulations.In a nutshell,this paper constitutes a tutorial on the JSCC scheme tailored to the needs of future 6G communications.
