摘要： A maximum likelihood detection (MLD) method is disclosed. Received data is processed to obtain preliminary parameters. An initial radius r is determined. r2 is multiplied by a corresponding scaling factor according to a partial Euclidean distance (PED) constraint function to determine the upper limit values of PED for each layer. It is examined whether a sub-lattice exceeds a search scope according to the upper limit values of PED for each layer to search a better solution by utilizing the preliminary parameters.

摘要： An exemplary embodiment of the present invention proposes a transmitter including a hierarchical modulator. The hierarchical modulator receives, jointed encodes, and maps a high-priority and low-priority bit-stream signals, so as to generate multiple mapping signal, wherein each mapping signal is the summation of a low-priority and high-priority mapping signals. The low-priority mapping signal is the complex number signal on the frequency domain to which part bits of the low-priority bit-stream signal are mapped, and the high-priority mapping signal is the complex number signal on the frequency domain to which part bits of the high-priority bit-stream signal are mapped. The pth low-priority mapping signal is related to (p+1)th low-priority mapping signal, and p is an even number or an odd number.

摘要： A method for removing ICI for a received symbol is provided. Firstly, a transmitted symbol is received via a wireless channel within a symbol time so as to obtain the received symbol. The transmitted symbol includes P identical original partial data, wherein P is a positive integer larger than 1. The received symbol includes P received partial data corresponding to the original partial data, respectively. Next, on a time domain at least two of the P received partial data are copied so as to obtain at least two copied partial data. Each copied partial data includes P copies of its corresponding received partial data. After that, an estimated ICI of the time domain is determined according to the product of a predetermined constant array and the difference between the copied partial data. Afterwards, the estimated ICI is subtracted from the received symbol so as to obtain an output symbol.
