摘要： A system and method for the efficient transmission of information in a code division multiple access (CDMA) wireless telecommunication system. The rate of reliable transmission is increased by implementing an orthogonal frequency-division multiplexing (OFDM) scheme in, for example, a direct-spread CDMA network, resulting in a multi-carrier CDMA (MC-CDMA) system. Information (such as voice and data), is encoded (205), divided, and spread across the frequency domain (255), rather than in the time domain as in traditional CDMA; the allowable transmission bandwidth is divided into a number of carriers. Using this scheme, a number of loading parameters such as code rate, data rate, and the number of streams into which the encoded data is divided may be varied to increase the performance of the system. Application of the variable loading parameter may be a function of channel quality, such as the presence of noise or the channel fading state.

摘要： A multi-level space time signal constellation that is optimized for use with a multi-carrier, multi-path communication scheme includes points on a first level separated from points on a mutually exclusive second level by a minimum distance that is based on a conditional probability distribution, preferably a Kullback-Leibler (KL) distance. Points within one level may be separated by a Euclidean distance, but spherical levels are rotated relative to one another to maximize a minimum inter-level KL distance. A receiver uses pilot symbols to estimate the channels and two-stage symbol detection, determining in one stage the constellation level and in another stage the point in the level. The receiver calculates a likelihood function based on a conditional distribution which does not reduce to the Euclidean-based nearest-neighbor detector. A single stored constellation may be scaled based on received signal to noise ratio. Each constellation defines n=2M real dimensions, wherein M is the number of transmit antennas.

摘要： A system and method for the efficient transmission of information in a code division multiple access (CDMA) wireless telecommunication system. To increase the rate of reliable transmission, an orthogonal frequency-division multiplexing (OFDM) scheme is implemented in a direct-spread CDMA network, this combination sometimes being referred to as multi-carrier CDMA (MC-CDMA). Information (such as voice and data), interspersed with a known pilot signal, is encoded and spread across the frequency domain, rather than the time domain as in traditional CDMA; the allowable transmission bandwidth is divided into a number of carriers. To achieve even larger transmission rates, the guardband between carriers is eliminated. To prevent interference, the number of pilot transmissions is reduced and a corresponding number of frequency bins at the border of an OFDM block are loaded with zeros. The receiver simply ignores these subcarriers when reconstructing the transmitted signal.

摘要： A hybrid receiver (606), and an associated method, for receiving a radio signal carrying transmitted data that is subject to distortion in the transmission channel. The receiver includes a plurality of stages that perform parallel interference cancellation (PIC) to establish successively more accurate estimates of the transmitted data, including a receiver first stage (611) being either a RAKE receiver or a linear minimum mean-square error (LMMSE) receiver, a second stage (620) including an LMMSE (626), and preferably a third stage (630) also including an LMMSE (636). Each stage processes the estimates of the transmitted signal provided by the stage preceding it to mitigate or eliminate as much transmission-channel interference as possible and prove a refined estimate for processing by subsequent stages. Improved channel estimation may be achieved by processing the pilot signal in similar fashion as well.

摘要： A generalized zigzag code is described where the code segments (each including one parity bit and information bits) of a block are not necessarily of uniform length. For coding rates in which the average code segment length is not an integer, all code segment lengths may be identical. The number of code segments depends on the coding rate and number of information bits in a block. At the encoder, parity bits are added to each string of information bits in a block to yield the code segments. For a punctured code, concatenated or not, the encoder may remove or not generate the punctured parity bits. At a decoder that operates at a rate different from the code rate of a received block, null parity bits are inserted. The received block has a number of code segments. The decoder increases the number of code segments by the addition of null parity bits, thereby reducing the coding rate to the rate of the decoder. Methods and apparatuses are detailed.
