Descriere completă

In this thesis, we propose data sharing schemes for§the cooperative diversity in a cellular uplink to§exploit spatial diversity and enhance throughput§performance of the system. Particularly, we consider§new two and three-or-more user decode and forward§(DF) protocols using space time block codes and also§amplify and forward (AF) protocols and evaluate the§performance of the above mentioned data sharing§protocols in terms of the bit error rate and the§throughput in an asynchronous code division multiple§access (CDMA) cellular uplink. We develop a linear§receiver for joint space-time decoding and multiuser§detection that provides full diversity and near§maximum-likelihood performance. We also focus on a§practical situation where inter-user channel is noisy§and cooperating users can not successfully estimate§other user''s data. We further design our system model§such that, users decide not to forward anything in§case of symbol errors. Channel estimation plays an§important role here, since cooperating users make§random estimation errors and the base station can not§have the knowledge of the errors or the inter-user§channels. We consider a training-based approach for§channel estimation.
