Patent ID: 8341467

Claim:
A method for determining a modulation form and a block length of a current transmission transmitted by a transmitter comprising: computing an average mutual information per bit based on a current channel signal-to-noise ratio and a plurality of previous transmissions, each previous transmission having a respective coded block length, modulation form, and signal-to-noise ratio; computing a block error rate for a plurality of block lengths and modulations based on the average mutual information per bit; determining a throughput of the current transmission using the block error rate; and determining the modulation and the block length of the current transmission based on an analysis the throughput; wherein the throughput is determined by η ⁡ ( t , m ) = 1 - P w ⁡ ( t , m ) ∑ j = 1 l - 1 ⁢ n j / q ⁡ ( Ω j ) + n t / q ⁡ ( Ω m ) wherein n is the throughput, P W is the block error rate, l is a cardinality of the current transmission, n j is a code length of the j th transmission, Ω j is a modulation form of the j th transmission, n t is a code length chosen so as to obtain a lower code rates, Ω m is chosen from a plurality of predefined modulation forms, and q( ) determines a number of bits per symbol of a particular modulation form.
