In contrast to the channel coding extensively investigated in various research-literatures on MIMO system, the source-coding method for the system is typically not expressly covered. The justification for this common approach is the Shannon Separation Theory, which states that source and channel coding can be separately done without affecting the system performance. More recent researches show that the Shannon Separation Theory does not bold for certain conditions, which encourage researches on joint source and channel coding methods. In this paper a preliminary joint source and channel coding in the form of Rate Compatible Punctured Convolutional Code (RCPC Code) applied as an Unequal Error Protection (UEP) to the source stream is proposed. The RCPC code is achieved by puncturing a low rate 1/N code periodically with period P to obtain a family of codes with rate P/(P + 1) where I can be varied between 1 and (N-1)P. Simulations are done to examine the performance of the code. Results show that the proposed RCPC code enables unequal error protection to the source information ordered with increasing importance. A further research is planned to implement RCPC on MIMO system . Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Lihat Sejarah Pengadaan  Konversi Metadata   Kembali
