Disclosed are a method for preparing a non-sintered shell-wrapped ceramsite using solid waste meanwhile immobilizing a heavy metal in river sediment, and a non-sintered river-sediment-based shell-wrapped ceramsite, which relate to the technical field of building materials. The disclosure combines river sediment with a solid waste powder and an alkali activating powder material, and adopts multiple-step granulations to realize particle size control and physical pore formation, thereby obtaining a non-sintered ceramsite. A sulfoaluminate cement and a Portland cement are used to encapsulate the non-sintered ceramsite and form a shell by wrapping, thereby preparing a non-sintered river-sediment-based shell-wrapped ceramsite with internal porosity and dense shell.

Disclosed herein are a fly ash-based foam geopolymer, a preparation method therefor, and the use thereof. The fly ash-based foam geopolymer is prepared from raw materials comprising the following components in parts by weight: 900-1000 parts of a fly ash-based material; 600-700 parts of a composite alkali solution; 0-10 parts of a thickening agent; 2-6 parts of a foam stabilizer A; 5-10 parts of a water reducer; and 20-40 parts of a foaming agent. The preparation method of the present application is simple, and processes such as ball milling, water washing and calcining do not need to be carried out on the raw materials, such that the investment in a grinding equipment, a water washing equipment, a sewage treatment equipment, and a calcining equipment is reduced, and the energy consumption and carbon emissions are reduced. The fly ash-based foam geopolymer prepared by using the fly ash-based material as the main raw material in the present application has a low apparent density and a high early strength, and can be used in the field of fabricated buildings.

A method for double weighting parallel interference cancellation in CDMA mobile communication system, integrates ideas of both partial weighting method and weighting method based on Bayes rule. When making a decision on each symbol of the user, calculating reliability coefficient of a decision result on the symbol of the user according to the weighting algorithm based on Bayes rule; weighting regenerated signal of the symbol of the user with the reliability coefficient. During process of MAI estimating and removing, obtaining the MAI on the expected user from weighted regenerated signal of other users in chip level; and then setting a weight value, weighting the MAI with the weight value. Finally, removing weighted MAI from received signal, which means partially removing MAI produced by other users on the expected user. At the same time, the present invention also discloses a double weighting PIC method with simplified algorithm, which transfers weighting in chip level to weighting in symbol level, replacing a Hyperbolic tangent decision with a piecewise linear decision method or a look-up table method.

The invention provides a method and apparatus for estimating flat fading channel in CDMA communication system, said method is implemented by using an adaptive forward prediction technique based on lattice filter and maximum likelihood technique of Viterbi algorithm. The adaptive lattice filter is used to carry out prediction of LS criteria on channel fading, and a maximum likelihood detection technique completes Viterbi algorithm in accordance with a channel fading value obtained by the prediction, thus obtaining final estimation and decision about the transmitting signals. The present invention has the advantages that it can obtain accurate result for channel estimation and sequence decision when it operates in the fast fading channel, and overcome fast fading influence due to motion speed up of mobile station, thereby satisfying mobile station speed and corresponding receiving performance required in 3G mobile communication.

A method and apparatus is provided for estimating a speed-adapted channel. The method is operative to use a known transmit symbol of guide frequency field in each slot to derive a corresponding fading value of the guide frequency field in the estimation to decide feedback channel by linear interpolation at first; and accumulate and average them for eliminating noise and performing interpolation process for the channel fading value in an outgoing data field; then according to the moving speed of a mobile station, adjust the length of the channel fading of the guide frequency which takes part in the accumulation to adapt to influence caused by different channel fading. It realizes the objectives of making more subscribers to get better and necessary services and making use of the system's resource effectively and reasonably.
