Multiuser
Indoor Wireless Access Methods and Systems Based on the OFDM
Transmission Technique

Abstract:
We
have presented a new power-efficient multi-user indoor wireless
system based on the OFDM transmission technique on the downlink.
In the new system subcarrier and modulation mode are allocated
such that the bit-rate and bit-error rate requirements of
all the active users are simultaneously satisfied. Such a
system is expected to be valuable in wireless multimedia communications
where high-speed downlink access is extremely important. Power
and bandwidth are two valuable resources in communications
and the new system allocates these resources in an efficient
manner. To our knowledge, there are no schemes which have
been presented to allocate resources in such an efficient
manner while taking care of the user requirements. Results
presented using simulations clearly illustrate the performance
advantages of the new scheme when compared with other schemes.
