| Abstract: | Performance of wireless communications systems is
degraded by fading, typically combated via spatial diversity by
multiple transmit and receiver antennas. Practical limitations
may limit their use; thus, cooperative transmissions have been
proposed to introduce diversity without the need for multiple
antennas. We propose a novel cooperative scheme that performs
distributed coding of user data. It needs each user transmit on
one single channel and allows large flexibility between rate and
diversity. A trade-off is increased complexity as more users are
required to be decoded simultaneously by the base station. We
present construction of the distributed code for different choices
of rates and diversity orders by means of simple linear block
codes, resulting in reduced complexity for decoding operations.
Achieved diversity order is bounded by the minimum distance of
the implemented distributed code. Performance of the scheme is
studied via analytical bounds and numerical simulations. |
