Abstract:
1. In a telecommunications receiver that includes a plurality of reception branches, a channelization method comprising the steps of: receiving an input data block from a reception branch, wherein said input data block has a length equal to N sampling data associated with the input data block into a first set of data samples and a second set of data samples, wherein the first set of data samples comprises even data samples, and wherein the second set of data samples comprises odd data samples; generating two complex blocks from the first set of data samples and the second set of data samples, wherein the first set of date samples is multiplexed into a real part of each of the two complex blocks, and wherein the second set of data samples is multiplexed into an imaginary part of each of the two complex blocks; multiplexing the two complex blocks into an N demultiplexing frequency domain data generated by the Fourier transform into one or more sequences of frequency blocks; wherein said step of demultiplexing the transformed blocks into one or more sequences of frequency blocks comprises the steps of: selectively collecting the frequency domain data associated with active channels, which is generated by the N extracting from said selectively collected frequency domain data, data associated with the real part of the two complex data blocks and data associated with the Imaginary part of the two complex data blocks; and combining the extracted data to form a necessary portion of an N
