Book Description
High data rate communication links operating under slow fading channel conditions may have interleaving memory requirements which are too large for practical applications. These requirements can be reduced by employing spacial diversity; however, a less costly alternative is to select coding and interleaving techniques that support memory efficient interleaving. The objective of this investigation has been to find coding and interleaving techniques with relatively small interleaving memory requirements and to accurately quantity these requirements. Toward this objective, convolutional and Ree-Solomon coding with single-stage and concatenated code configurations were evaluated with convolutional interleaving and differential phase shift keying (DPSK) modulation to determine their interleaving memory requirements. Code performance for these link selections was computed by high-fidelity link simulations and approximations over a wide range of E sub b/N sub 0 and interleaver span-to-scintillation decorrelation times (T sub il/Tan sub 0) and the results of these evaluations were converted to interleaving memory requirements. Interleaving delay requirements were also determined and code selections with low interleaving memory and delay requirements were identified.
