Abstract:
|
The convergence of cellular phones, the Internet, and laptop computers into a single small, lightweight, wireless information appliance drives a need for a high data rate, low-power digital wireless communication link to enable the creation of such a device. A simulation environment supporting rapid prototyping is developed, and used to evaluate the real-time data-rate performance of these receivers implemented on a multiprocessor DSP board. Simulations of a multiprocessor implementation of joint multiuser channel estimation and detection algorithms is projected to achieve combined perform-ance of 15.6 Kb/user/sec for 10 users. Performance gains over a single-processor implementation range from 5% for the three-user case to 69% for a 15 user case. |
