Patent ID: 6912195

Claim:
A transmitting device having one or more transmission branches, each transmission branch receiving a time-domain signal, said transmitting device comprising: a first set of one or more modules operable to transform each time-domain signal into a frequency-domain signal; a second set of one or more modules operable to apply a weight to each frequency-domain signal to form one or more weighted frequency-domain signals with each weighted frequency-domain signal being a function of each frequency-domain signal a third set of one or more modules operable to transform each weighted frequency-domain signal into a weighted time-domain signal; a fourth set of one or more modules operable to add a cyclic redundancy to each weighted time-domain signal to form a corresponding weighted redundant time-domain signal, wherein the cyclic redundancy is according to: x ^ j ⁡ [ i ] = { ⁢ x j ⁡ [ i + N - L cp ] , ⁢ 0 ≤ i ≤ L cp - 1 ⁢ x j ⁡ [ i - L cp ] , ⁢ L cp ≤ i ≤ N + L cp - 1 or x ^ j ⁡ [ i ] = { ⁢ x ^ j ⁡ [ i ] , ⁢ 0 ≤ i ≤ N - 1 ⁢ x j ⁡ [ i - N ] , ⁢ N ≤ i ≤ N + L cp - 1 ⁢ or any combination of the two; and a fifth set of one or more modules operable to transmit the weighted time-domain signal.
