in this paper the problem of minimizing the total transmitting power subject to a fixedtotal bit rate in ofdm systems is considered. upper bounds on transmitting power and bit rate ofeach subcarrier can also be taken into account. in practice, the number of bits of each subcarriershould be integer and nonnegative. in this paper an analytical optimal solution is derived for thecase of assuming t...

The Consortium on Automated Analytical Laboratory Systems (CAALS) has been formed with interested parties from the private sector and other government agencies at NIST to foster the creation of automated chemical analysis systems that will improve the quality of analytical data, facilitate the entire analytical process, and promote the standardization and transfer of analytical methods, while p...
